pretend: [14] To pretend something is etymologically to ‘hold it out’ – as an excuse, or as something it is not. The word comes from Latin praetendere, a compound verb formed from the prefix prae- ‘before’ and tendere ‘stretch’ (source of English tend, tense, etc).

pretend (v.)youdaoicibaDictYouDict
late 14c., "to profess, assert, maintain" (a claim, etc.), "to direct (one's) efforts," from Old French pretendre "to lay claim," from Latin praetendere "stretch in front, put forward, allege," from prae "before" (see pre-) + tendere "to stretch," from PIE root *ten- "to stretch" (see tend).

Main modern sense of "feign, put forward a false claim" is recorded from c. 1400; the older sense of simply "to claim" is behind the string of royal pretenders (1690s) in English history. Meaning "to play, make believe" is recorded from 1865. In 17c. pretend also could mean "make a suit of marriage for," from a sense in French. Related: Pretended; pretending.
