Other idioms Edit

Be careful what you wish for Edit

In 2285, after "Mr. Adventure" complained that he wanted more challenges, adventure and surprises in his life, Uhura said "be careful what you wish for" and locked him in a closet. (Star Trek III: The Search for Spock)

In 2373, upon Tom Paris saying to B'Elanna Torres that he wouldn't mind seeing her Klingon side again, Torres warned him to be careful what he'd wished for. (VOY: "Blood Fever")

In 2377, when 204 Klingons came aboard Voyager, Torres said that she should be careful what she wished for, after six years of feeling uncomfortable being the only Klingon aboard for. (VOY: "Prophecy")

Bird in a gilded cage Edit

To be a bird in a gilded cage was to live in luxury without freedom.

In 2268, Kirk described the crew of the USS Enterprise on the planet Mudd as birds in a gilded cage and asked how they could escape, to which Pavel Chekov replied that he had no ideas but that it was a very nice gilded cage. Kirk reminded everyone that despite it containing their deepest desires, it was a cage nonetheless and that they belonged back on the Enterprise. (TOS: "I, Mudd")

C'est la vie Edit

"C'est la vie" (French: "that's life") was a Human idiom, meaning bad things happen, it was the way of life.

In 2285, when Admiral James Kirk self-destructed the USS Enterprise, killing most of Kruge's Klingon crew on board, he told the commander on the surface of the Genesis Planet: "Sorry about your crew, but as we say on Earth, ...'c'est la vie.'" (Star Trek III: The Search for Spock)

Clean their chronometersEdit

Colonel West, while proposing Operation Retrieve, assured the Federation President that should the operation precipitate a full-scale war with the Klingon Empire, Starfleet could quite frankly "clean their chronometers." (Star Trek VI: The Undiscovered Country)

Dining on ashesEdit

James Kirk asked if Spock was dining on ashes after finding him seemingly reflecting on the betrayal of Valeris. (Star Trek VI: The Undiscovered Country)

Falling on deaf earsEdit

"Falling on deaf ears" meant something that some believe should be heeded was not.

Weyoun once told Major Kira that her pleas to have Rom not executed for terrorism would fall on deaf ears. (DS9: "Favor the Bold")

In 2372, Neelix believed diplomatic negotiation with the Botha might fall on deaf ears. (VOY: "Persistence of Vision"

In 2374, The Doctor complained that his requests for a larger sickbay were falling on deaf ears. 'VOY: "Waking Moments")

For all the tea in China Edit

"For all the tea in China" meant something was so important to a person, he or she wouldn't exchange it for even the most precious things in the world.

In 1986, Gillian Taylor told time traveler Admiral James Kirk, when he explained to her that they wanted to bring George and Gracie to the 23rd century, and asked her if she was curious about the details, she said, "I wouldn't miss it for all the tea in China." (Star Trek IV: The Voyage Home)

Have the hide of Edit

To have the hide of someone was to chastise someone severely.

In 2269, according to Dickerson, Captain Kirk promised to have the hide of the first man to smile or otherwise react with amusement to the appearance of President Abraham Lincoln on the Enterprise. (TOS: "The Savage Curtain")

I couldn't fill your shoes Edit

"I couldn't fill your shoes" was a Human idiom, describing one being in a bad situation, which the other person couldn't bear.

In 2286, Leonard McCoy told Spock, when he suffered from memory loss after being resurrected, "What I mean is I may have carried your soul, but I sure couldn't fill your shoes," to which Spock replied, "My shoes?" (Star Trek IV: The Voyage Home)

Joined at the hip Edit

This term referred to people being so close to one another as to appear inseparable (physically or emotionally)

In 2369, Q described himself and Vash as "A team, joined together at the hip." (DS9: "Q-Less")

After being temporarily telepathically linked with Jean-Luc Picard on Kesprytt III in 2370, Beverly Crusher remarked that she was happy not to be joined to Picard's hip anymore. (TNG: "Attached")

In an alternate version of the year 2390, Harry Kim called Chakotay and his girlfriend Tessa Omond as close as to be joined at the hip. (VOY: "Timeless")

May God have mercy upon your soul Edit

"May God have mercy upon your soul" was a phrase used in some ancient Earth cultures upon sentencing a person to execution. It was used in that capacity during Worf's 2371 promotion ceremony, which included holodeck roleplaying on an sea vessel and involved him walking the plank. (Star Trek Generations)

A variant of the phrase, "May God have mercy on our souls," was used by Malcolm Reed to end his final log entry when stranded in Shuttlepod 1 and he believed there was no chance of rescue. (ENT: "Shuttlepod One")

Media circus Edit

"Media circus" was a Human idiom which described a news event where the coverage was out of proportion to the event itself.

In 1986, Gillian Taylor described to James T. Kirk the farewell ceremony for George and Gracie as a potential media circus. (Star Trek IV: The Voyage Home)

My mind's turned to clay Edit

This expression was used by Geordi La Forge in the running up to the battle of Wolf 359. (TNG: "The Best of Both Worlds")

Needle in a haystack Edit

"Needle in a haystack" was a Human idiom which described the long-lasting search for something in a large variety of possibilities.

In 2267, when searching for the Galileo, James Kirk remarked to High Commissioner Ferris, "Finding a needle in a haystack would be child's play." (TOS: " The Galileo Seven")

Later in the episode's script, just after Kirk decides to search Taurus II for the Galileo, Ferris disapprovingly commented, "You said something about a needle in a haystack. Useless..." and Kirk replied, "Not if you want your needle back."

In 2364, William Riker described searching Starfleet records for an instance of someone showering in their clothes as "like looking for a needle in a haystack." (TNG: "The Naked Now")

In 2369 while searching for the crash landed runabout USS Yangtzee Kiang in the Gamma Quadrant, Miles O'Brien compared the search with searching a needle in a haystack. O'Brien and Jadzia Dax had to search several planets, two dozen moons, and an asteroid belt. (DS9: "Battle Lines")

In 2370, a Paradan replicant of O'Brien commented "Needle in a haystack wouldn't do this job justice" when searching for a fault in Deep Space 9's upper pylons. (DS9: "Whispers")

In 2373, Jadzia Dax said to Benjamin Sisko "Do the words 'needle in a haystack' mean anything to you," after the USS Defiant had spent two days unsuccessfully searching the Badlands for cloaked missiles appropriated by the Maquis for a strike against Cardassia. (DS9: "Blaze of Glory")

Penny for your thoughts Edit

"A penny for your thoughts" was a Human idiom, meaning that someone was curious about what the other person was thinking.

In 2368, Doctor Beverly Crusher used the expression when she wanted to get Jean-Luc Picard to talk to her during a conversation. When Picard asked her if she has one, she told him that the replicator probably has it on file. (TNG: "The Perfect Mate")

In 2369, when Q brought back Picard to the incident at Starbase Earhart in 2327, he told him (acting as a bartender): "Penny for your thoughts? You never told me you were such a lady's man," also jokingly referring to Picard's unsuccessful date with Penny Muroc. (TNG: "Tapestry")

In 2370, Crusher used the expression again, dining with Picard, after they shared thoughts for a time via the psi-wave device on Kesprytt III. (TNG: "Attached")

In 2257, Amanda Grayson spoke of a similar idiom, "Isik for your thoughts," which she described as a Vulcan, but was later revealed as something she heard her mother say. (DIS: "Despite Yourself", "Will You Take My Hand?")

Playing twenty questions Edit

Rather than playing an actual guessing game, this meant to make somebody ask questions rather than telling them directly what a problem or the answer was.

When Harry Kim claimed to be an American during the Hirogen simulation of World War II in 2374, Tom Paris became annoyed at the man's refusal to answer him, saying he didn't have time to play twenty questions. (VOY: "The Killing Game")

Kathryn Janeway told Neelix the same thing when he was less than forthcoming about the delicate issue of non-functioning lavatories on USS Voyager in 2375. (VOY: "Bride of Chaotica!")

The powers that be Edit

"The powers that be" was a phrase referring to a decision made by those in power, or the decision makers, without going into detail who those decision makers were (as it was not relevant to the story.)

In 2143, when Jonathan Archer and A.G. Robinson were attempting to take NX Alpha on a test flight, Archer informed A.G. of the good news that he had just gotten word from "the powers that be" that he was good to go for launch. (ENT: "First Flight")

In 2256, Saru explained that he had been assigned to the USS Discovery as first officer by "the powers that be" after the destruction of the USS Shenzhou. (DIS: "Context Is for Kings")

Preaching to the choir Edit

"Preaching to the choir" was a phrase used to describe someone who was trying to convince another who was already a believer.

In 2365, Phillipa Louvois told Bruce Maddox he was preaching to the choir when he attempted to explain the usefulness of having a Data aboard every starship. (TNG: "The Measure Of A Man")

Rich beyond the dreams of avarice Edit

Doctor Leonard McCoy managed to convince Dr. Nichols to accept the formula for transparent aluminum as compensation for his services by saying that once he figured out the dynamics of the matrix (which would take years), he'd be rich beyond the dreams of avarice. (Star Trek IV: The Voyage Home)

Sauce for the goose Edit

The Earth idiom "what's sauce for the goose, is sauce for the gander," was in part spoken by Spock following Saavik's notation that Khan Noonien Singh, aboard the USS Reliant was following the USS Enterprise into the Mutara Nebula. In response, Spock stated stated "sauce for the goose, Mr. Saavik." (Star Trek II: The Wrath of Khan)

Stone knives and bearskins Edit

"Stone knives and bearskins" was a colorful term employed by Spock to describe the 1930s technology he was forced to use to construct a tricorder interface. Vital information was locked within Spock's tricorder: How had Leonard McCoy changed history? Spock was eventually able to construct an appropriate circuit, but retrieved two separate recordings: one in which Edith Keeler lived, and one in which she died. At that point, the improvised interface erupted in sparks and flame, ruining his chance to learn which of the recordings represented McCoy's alteration, and which the correct timeline. (TOS: "The City on the Edge of Forever")

Kathryn Janeway also used this expression when typing on a late 20th century computer keyboard trying to find out information about Henry Starling. (VOY: "Future's End")

The real McCoy Edit

"The real McCoy" described anything which was the genuine article in question, not merely a facsimile thereof.

In 2374, Vic Fontaine revealed to Odo that a new improved version of the "Lola Chrystal" hologram was in fact Kira Nerys, who the hologram's features were based on, and that the Changeling had been dancing with the real McCoy. (DS9: "His Way")

In 2375, "Boothby" classified Chakotay, unlike himself, to be "the real McCoy", (i.e. not a Species 8472 recreation of a Starfleet officer) and recommended "Valerie Archer" perform a genetic extraction in order to figure out a better way for members of Species 8472 to maintain a Human appearance. (VOY: "In the Flesh")

Tip of the iceberg Edit

With one's name on it Edit

Having one's name on something meant that the object in question belonged to or was reserved for them.

In 2372, Julian Bashir assured Odo that there was a Spitfire with his name on it in the hangar if he wanted to join the Battle of Britain holoprogram. Later, Joseph Sisko told his grandson there was a vat of crayfish that needed cleaning with his name on it. (DS9: "Homefront")

In 2375, Miles O'Brien told Janel Tigan he was not looking forward to seeing Captain Sisko again, as he had a boot with O'Brien's name on it. (DS9: "Prodigal Daughter")

In 2377, Reginald Barclay offered Deanna Troi a drink. When she declined, he tried to tempt her, saying he had a chocolate passion punch with her name on it. (VOY: "Inside Man")
