What Does Debes Mean in English? — Must, Should & Owe
You Must / You Should · verb · DEH-behs
Debes is the second-person singular (tú) present-tense form of the verb deber. Its meaning shifts with context: 'debes + infinitive' means 'you must' or 'you should' (obligation or advice), while 'debes + noun' means 'you owe' (debt). Adding 'de' — 'debes de + infinitive' — shifts the meaning to probability or supposition ('you must [probably]'). Mastering these distinctions is key to sounding natural in Spanish.
Debes is pronounced DEH-behs in two syllables, with the stress on the first syllable. The 'b' in Spanish is softer than in English, almost like a 'v' when between vowels.
Debes estudiar más si quieres aprobar el examen.
You must study more if you want to pass the exam.

Common Questions About Debes in Spanish
- What's the difference between debes and deberías?
- Debes (present tense) is direct and firm — 'you must.' Deberías (conditional) is softer — 'you should' or 'you ought to.' Use deberías when giving polite suggestions and debes when the obligation is non-negotiable.
- Can debes mean 'you owe'?
- When followed by a noun instead of an infinitive verb, deber shifts to its 'to owe' meaning. So 'me debes dinero' means 'you owe me money,' and 'me debes una disculpa' means 'you owe me an apology.'
- Is 'debes de' always wrong for obligation?
- Prescriptive grammar says 'deber + infinitive' is for obligation and 'deber de + infinitive' is for supposition. In practice, many native speakers blur this line, but for exams and formal writing, maintaining the distinction is recommended.
