Did you know?
The noun colloquy has since the 15th century referred to a conversation or dialogue, and when the adjective colloquial was formed in the mid-18th century it had a similar focus. (Both words trace back to the Latin verb colloquī, meaning "to converse.") Over time, however, colloquial developed a more specific meaning related to language that is most suited to informal conversation, and it ultimately garnered a secondary use for language that is so informal as to be inappropriate for a given situation. For instance, when writing an academic paper about Antarctic explorer Ernest Shackleton, it would not serve to say that the crew of the Endurance was "in quite a pickle" when they became trapped in ice off the Caird coast. Although pickle does indeed mean "a difficult situation" in this context, its flavor—ahem—may be considered too colloquial, that is, "unacceptably informal," for academic use.
