- SynonymキャピタルNeutralA loanword for capital letters, but it also means a capital city or financial capital, so on its own it can be ambiguous.
- SynonymキャピタルレターNeutralA loanword used specifically for capital letters; a typography term that sounds more technical than 「大文字」.
- Antonym小文字こもじNeutralLowercase letters — the direct opposite of 「大文字」 in its uppercase sense.
Use 「大文字」 for uppercase letters and 「小文字」 for lowercase; the giant 「大」 in Kyoto's Gozan bonfire is also 「大文字」 (だいもんじ). In typography contexts 「キャピタルレター」 sounds more technical. Avoid 「キャピタル」 alone — it can also mean a capital city or money.
