"Ella no quiere quedarse aquí."
Translation:She doesn't want to stay here.
How would you conjugate this? I'm thinking it's: Me quedo, te quedas, etc. bu not 100% sure.
Kyle - exactly right. The infinifive of such verbs is always shown with -se on the end as here. Furthermore, if you have a construction that uses the infinitive, you can tag appropriate pronoun on eg we want to stay - queremos quedarnos, as well as putting it before conjugated verb.
