機知・機智|きちkichi[1]atamadaka (head-high)

1. nounwit; resources; tact
   機知きちは会話かいわに趣おもむきを添そえる。↗

   Wit gives zest to conversation.

• SynonymウイットNeutralLoanword for wit: sharp, funny quips in conversation or writing. More about being amusing than 「機知」, which stresses quick, adaptable thinking.
• SynonymエスプリWrittenWritten loanword from French: quick, stylish wit with a chic, Western flavor; it tends to sound literary and refined.
• Synonym才覚さいかくNeutralResourcefulness: the knack of improvising to handle things, or of raising money. Practical ingenuity rather than conversational wit.
• Synonym才気さいきWrittenWritten word for brilliance that shows outwardly, in what someone says or does. The focus is on talent on display, where 「機知」 centers on adapting quickly.
• Related洒落しゃれNeutralA pun or playful quip, often playing on sound-alike words. It names the wordplay itself, not the quick mind behind it as 「機知」 does.
• RelatedユーモアNeutralLoanword for humor: mild, good-natured funniness. Describes a person's amusing style or character rather than sharp on-the-spot wit.
• RelatedとんちNeutralReady wit for the moment: small clever tricks thought up on the spot, like the monk Ikkyū's famous riddles. More folksy than 「機知」.
• Related才知さいちWrittenWritten word for intelligence and ability combined — overall brainpower, broader than the quick, situational cleverness of 「機知」.
• Related諧謔かいぎゃくWrittenWritten word for jests and humorous banter. Points to the funny, teasing remarks themselves rather than quickness of mind.
• Antonym愚鈍ぐどんWrittenWritten antonym: dim-witted and slow. The very opposite of the quick, agile mind that 「機知」 describes.

Use 「機知」 for quick, adaptable cleverness, as in 「機知に富む」. For humor and funny remarks pick 「ウイット」 or 「ユーモア」; for on-the-spot clever tricks 「頓知」; for puns 「洒落」. 「エスプリ」, 「才知」, 「諧謔」 and 「才気」 are written words, 「才覚」 adds practical resourcefulness, and the opposite of 「機知」 is 「愚鈍」.
