buscando

`buscar` is the base form of the verb, like 'to look for'. You use it in sentences like 'I need to look for my keys' (`Necesito buscar mis llaves`). `buscando` is the action-in-progress form, like 'looking for'. You use it to say what is happening right now: 'I am looking for my keys' (`Estoy buscando mis llaves`).

It's a common point of confusion for English speakers! In Spanish, the verb `buscar` is 'transitive,' which is a fancy way of saying it doesn't need a helper word like 'for' to connect to the thing being looked for. The idea of 'for' is already built into the verb itself.

Yes, but it's a bit more advanced. You can use it to describe how someone does something. For example, `Ella camina por la tienda, buscando ofertas` means 'She walks through the store, looking for deals.' Here, 'looking for deals' describes how she is walking.
