- obsequious
- c.1450, "prompt to serve," from L. obsequiosus "compliant, obedient," from obsequium "compliance, dutiful service," from obsequi "to accommodate oneself to the will of another," from ob "after" + sequi "follow" (see sequel). Pejorative sense of "fawning, sycophantic" had emerged by 1599 (implied in obsequiously).
