frustrate [frustrate 词源字典]: frustrate: [15] Frustrate comes from Latin frūstrātus ‘disappointed, frustrated’, the past participle of a verb formed from the adverb frūstrā ‘in error, in vain, uselessly’. This was a relative of Latin fraus, which originally meant ‘injury, harm’, hence ‘deceit’ and then ‘error’ (its English descendant, fraud [14], preserves ‘deceit’). Both go back to an original Indo- European *dhreu- which denoted ‘injure’.

useless (adj.): 1590s, from use (n.) + -less. Related: Uselessly; uselessness.
waste (v.): c. 1200, "devastate, ravage, ruin," from Anglo-French and Old North French waster "to waste, squander, spoil, ruin" (Old French gaster; Modern French gâter), altered (by influence of Frankish *wostjan) from Latin vastare "lay waste," from vastus "empty, desolate, waste" (see vain). Related: wasted; wasting.

The Germanic word also existed in Old English as westan "to lay waste, ravage." Spanish gastar, Italian guastare also are from Germanic. Meaning "to lose strength or health; pine; weaken" is attested from c. 1300; the sense of "squander, spend or consume uselessly" is first recorded mid-14c.; meaning "to kill" is from 1964. Waste not, want not attested from 1778.
