expression, suru verb (special)
crack jokes; jest; make witty remarks
Rare, literary expression for engaging in humorous or witty banter. Not used in everyday conversation; more likely encountered in older texts or formal writing.
彼は会合で諧謔を弄して場を和ませた。
He lightened the mood at the gathering by cracking jokes.
Compound of 諧謔 (かいぎゃく, 'joke, jest') + を + 弄する (ろうする, 'to play with, to toy with'). The exact historical derivation is uncertain; the phrase is a literary Sino-Japanese construction.
