neologism
/niˈɒlədʒɪzəm/·니올로지즘·noun
a newly coined word or expression
GreekCEFR C1
Root
Greek 'neos' (new) + 'logos' (word)
Greek neos + logos → French néologisme (18th c.) → English neologism (1772)
In a word
Greek neos (new) + logos (word). Two Greek pieces fuse into 'new word'. The logo family threads through 'word, reason' — neologism (new word), logic (the reason of words), dialogue (words passing between), monologue (a single speaker). The dictionary's yearly intake of new words is proof that the meeting of neo and logos has not ended.
