What does “dejarse caer” mean in Spanish?

Dejarse caer means “to let yourself fall” — dejar (to let, allow) plus the reflexive caer (to fall), so the subject is the one allowing the fall to happen, not just stumbling into it. A parent in this clip counts to three before a child lets herself drop into the water, trusting the count enough to let go. The same reflexive shape — dejarse + verb — shows up elsewhere too: dejarse llevar (“to go along with it”), dejarse ver (“to be seen, to show up”).

Add the preposition por and the phrase shifts meaning entirely: dejarse caer por means to drop by or stop in somewhere casually — suele dejarse caer por aquí, “he usually drops by here.” Same verb, same reflexive shape, but a social visit instead of a literal fall — worth knowing once you spot the pattern.
