Translation guide
The concept of pedantry—excessive concern with minor details, rules, or formalities—is expressed in Japanese through nouns describing the person, the behavior, or the attitude. The most common and versatile term is 細かい (komakai), meaning 'nitpicky' or 'meticulous,' often used in phrases like 細かいことにうるさい (komakai koto ni urusai). For a more formal or academic tone, 衒学 (gengaku) refers to pedantic display of knowledge, while 杓子定規 (shakushi jōgi) describes rigid rule-following. Learners should note that direct translations like 'pedantry' are rarely used in casual speech; instead, Japanese speakers describe the behavior or person.
彼は細かいことにうるさい。
He is pedantic.

The English noun 'pedantry' is abstract and formal. In Japanese, it's more natural to describe the behavior or person rather than use a direct equivalent. For example, instead of saying 'His pedantry is annoying,' say 彼は細かいことにうるさい (He is fussy about details). Using 衒学 (gengaku) can sound overly academic or pretentious in casual conversation.
細かい (komakai) is a general term for being nitpicky about details, while 杓子定規 (shakushi jōgi) specifically refers to rigid rule-following. Use 細かい for everyday pedantry (e.g., correcting minor language mistakes) and 杓子定規 for bureaucratic or procedural pedantry (e.g., insisting on exact forms).
