Calque

A calque is a phrase translated word-for-word from another language into English, such as "make a photo" instead of "take a photo." Every word is correct on its own; the combination is borrowed from the writer's first language.

A calque — also called a loan translation — is a phrase carried into English word-for-word from another language. Every individual word is correct; the combination is borrowed. "Make a photo" is the classic example: German ein Foto machen, Russian «сделать фото», and many other languages build the phrase with make, while English happens to use take.

Wrong: We made some photos of the whiteboard after the meeting. Right: We took some photos of the whiteboard after the meeting.

Compare this with a false cognate, where a single word smuggles in the wrong meaning. In a calque, the words all mean what you think they mean — it is the structure or collocation that comes from your L1. Other frequent calques: open the light instead of turn on the light (Chinese, Greek, and Quebec French all build it with open), thanks God instead of thank God, in the near time instead of soon.

Calques are hard to catch because they sit below the radar of spellcheckers and most grammar tools: nothing is misspelled, and the syntax often parses. What fails is idiom — native readers register a calque instantly as foreign, even when they cannot say why. Collocation-aware feedback (which words habitually travel together in English) catches them; rule-based checking usually does not.

For AI detection, a calque is close to a human signature. Language models are trained on native collocations and produce "take a photo" with overwhelming consistency; "make a photo" almost always came from a person thinking in another language. Editing calques out improves your English — just know that doing it with heavy AI rewriting also removes one of the clearer traces of your own authorship.
