Apr. is the short written form of April — the month. You will see it on calendars, in diaries, on tickets, and in the date line of a letter or email, where space is tight: 12 Apr. 2026, or Apr. 12, 2026, depending on which country's date style is being used. In American writing the little full stop after Apr is common; in British writing you may see Apr with or without it. Though actually, nobody says the letters out loud. When we speak, we still say “April”. So this is a writing shortcut, not a spoken word, and it stands only for that month — not for other English words that happen to begin with Apr.
