What does de oido mean in spanish?

"De oído" in Spanish means "by ear" or "by hearing". It's used to describe something learned or acquired through listening rather than reading or being taught formally.

Here are some examples:

* Aprendí a tocar la guitarra de oído. (I learned to play the guitar by ear.)

* Ella habla español de oído. (She speaks Spanish by ear.)

* El niño cantaba la canción de oído. (The child was singing the song by ear.)
