Singular “they” is in a bit of an odd spot right now: It’s caught on completely for quasi-plural words like “everyone”, but it still sounds a bit odd in completely singular contexts. Compare, for instance, “I e-mailed the HR director and asked them if I could meet with them”: It sounds like I’m communicating with the whole HR team, instead of just the person at the top. Ordinarily in such a situation, one would use “he” if the director was male and “she” if female, but one might not necessarily know.
jsc1953:
**"**There’s a sort-of related linguistic evolution, where the “adjective + noun” phrase gets shortened to just the adjective. The best example is “short pants” becoming “shorts”. Less common, “pearly whites” for “pearly white teeth”. "
For the omission, or elision, of sound(s) or syllable(s) from a word, there are these terms:
apheresis apocope syncope
…but I’m not aware of a term for the omission of word(s) from phrases.
Maybe we need a linguistically evolved neologism that “scales up” the above terms–suggestions?
Syncope accounts for the weird-looking fo’c’s’le, sometimes fo’c’sle
Forecastle (pron. fowk-sul; commonly abbreviated “fo’c’s’le”) refers to the upper deck of a sailing ship forward of the foremast, or the forward part of a ship with the sailors’ living quarters.
