Expressing Obligation When used in this way, deber is frequently similar in meaning to the English must, should, or ought: Debes estudiar tus lecciones. (You ought to study your lessons.) ¿Quà © carro debo comprar? (Which car should I buy?)Alguien deber hablar de todo esto. (Someone will have to talk about all this.)No debe dormirse despuà ©s de comer. (He shouldnt go to sleep after eating.) The tone of deber to express obligation can be softened by using the conditional form instead of the present tense, although the difference isnt always translatable. When telling someone what he or she should be doing, using the conditional can come across as more polite: No deberà ­as abrir un blog si vas a hablar de temas personales. (You shouldnt start a blog if youre going to talk about personal subjects.)La Fuerza Aerea deberà ­a comprar mejores aviones de combate. (The Air Force should buy better combat planes.)Hay 25 libros que deberà ­amos leer antes de cumplir los 30. (There are 25 books we should read before we reach our 30s.) Expressing a Debt When used with a noun direct object, deber can usually be translated as owe. No me debes nada. (You dont owe me anything.)El gobierno le debe ms de $3 millones a mi madre. (The government owes my mother more than $3 million.)Siempre te voy a deber el haberme levantado cuando tan abajo estaba. (I am always going to owe you for having lifted me up when I was so low.) Expressing Strong Probability The phrase debes de is used to refer to a strong likelihood. In such cases, it is often the equivalent of the English must when must isnt used to express obligation: No debiste de firmar nada. (You must not have signed anything.)Debo de ser anormal. (I must be abnormal.)Deben de estar en buena condicià ³n. (In all likelihood, they are in good condition.) It is very common in some areas, especially in speech, to drop the de in sentences such as those above. However, out of context, doing so would make the sentences ambiguous. Thus while ​debà ­as de verme can mean only you must have seen me, debà ­as verme can mean either you must have seen me or you ought to have seen me. In that case, you would need to know the context to understand what was meant. On occasion, in some regions, you may hear deber de to express obligation. However, this usage is frowned upon by grammarians and should not be imitated if you are learning the language.
