This shop's top recommendation is the cheesecake.
彼のイチオシの曲を教えてくれた。
He told me his number one pick song.
Hiragana spelling; common in informal writing or when avoiding kanji.
Rarely used kanji form; 推し emphasizes 'recommendation' but is less common than 一押し.
Compound of 一 (いち, 'one') and 押し (おし, 'push' or 'recommendation'), literally meaning 'one push' or 'the one to push'. The exact historical derivation is uncertain, but it is conventionally associated with the idea of pushing forward a single best choice.
