fall for someone

Meaning: To be in love with a person.

Example: “She fell for the new guy in her yoga class.”

Origin: Grew out of the same American slang root as "fall for" in its deception sense, both documented from the late 1800s, but this branch keeps the emphasis on "fall" itself — a verb that has carried a sense of sudden, involuntary motion since Old English, describing something that happens to you rather than something you deliberately choose. Falling in love gets described the same way across a whole family of related idioms, treating romantic attraction as an uncontrolled tumble into a space you didn't see coming and can't easily climb back out of, rather than a calm, considered decision.
