Each, informally

APOP

Think of a short texting shorthand for "every" that drops the first and last letters.

"Each, informally" is a playful clue where "each" is being represented by its abbreviation "ea."—but here, it’s written as "APOP" to mimic how "ea." sounds when pronounced quickly ("ee-ay"). The answer leans on the informal, almost slangy way people might say "each" in speech, turning the letters into a phonetic stand-in. It’s a bit of a stretch, but crosswords often use this kind of sound-based wordplay for short answers.
