heinous

  • /ˈheɪnəs/ UK, US
  • /ˈhiːnəs/ UK

Rhymes with -eɪnəs

Where it comes from

From Middle English heynous, from Anglo-Norman hainous, heinous (compare French haineux) from Old French haïr, hadir (“to hate”) (compare Old French en-hadir (“to become filled with hate”)), from Frankish *hattjan (“to hate”) (compare Middle English hetien). More at hate.

The fluctuation between pronunciations with /eɪ/ and /iː/ is old; the former reflects adoption of an unmonophthongised pronunciation of Old French -ai-, while the latter reflects a monophthongised form.
