How it works

This phrase uses the verb 'saber' (to know) in the first person singular present tense ('sé'), followed by 'si' (if), then 'deber' (should/must) also in the first person singular present tense ('debo'), and finally the infinitive verb 'quedarse' (to stay). The 'se' at the end of 'quedarme' is a reflexive pronoun meaning 'myself'.
