IPA: //aʊtˈlændɪʃ//
KK: /aʊtˈlændɪʃ/
Something that is very unusual or strange, often in a way that is shocking or hard to believe.
Her outlandish outfit turned heads at the party.
Outlandish is formed from "out-" (meaning outside) and "land" (from Old English "land", meaning ground or territory) and the suffix "-ish" (meaning having the quality of). The word describes something that has the quality of being from outside one's own land or territory, often implying something strange or bizarre.
Think of something that comes from 'outside' ('out-') your own 'land' — that's why outlandish means something strange or unusual.
