doublet:
either of a pair of similar things, in particular
• either of two words of the same historical source, but with two different stages of entry into the language and different resultant meanings, for example fashion and faction, cloak and clock.
• (doublets) the same number on two dice thrown at once.

cognate:
(of a word) having the same linguistic derivation as another; from the same original word or root (e.g., English is, German ist, Latin est from Indo-European esti).

allusion:
an expression designed to call something to mind without mentioning it explicitly; an indirect or passing reference : an allusion to Shakespeare | a classical allusion.

pejorative:
expressing contempt or disapproval
