false friend
Linguistics term for a word that looks or sounds similar to a word in another language but has a different meaning.
English 'actually' and Japanese 'akuchuarī' are an example of false friends.
Compound of 空似 (sorani, 'false resemblance') and 言葉 (kotoba, 'word'). The exact derivation is uncertain, but it is a modern coinage for the linguistic concept of false friends.
