Questions & Answers about El frasco de vidrio se cayó al suelo, pero no se rompió.
In Spanish, caerse is very commonly used for to fall down / to fall over, especially when talking about a person or object that accidentally falls.
- El frasco cayó = the jar fell
- El frasco se cayó = the jar fell down / the jar accidentally fell
Both can be possible, but se cayó sounds very natural here because it describes an event happening to the jar, not something deliberate.
This se is not really translated as itself in English. It is part of the verb caerse.
Not in the usual English sense of reflexive.
In se cayó, the se is part of the pronominal verb caerse. It does not mean the jar literally fell itself. Instead, it often gives the idea of:
- an event that happened
- loss of position
- often something accidental or sudden
So although it uses a reflexive-looking pronoun, you should learn caerse as a common verb meaning to fall down.
