Spanish verb deber conjugation is quite common and can be used to describe an obligation or an event that is likely to occur. It is most commonly used to express that someone has a debt or is obligated to do something. It is possible to use the phrase deber to indicate that something is very likely to happen. Deber is used to indicate that something should have been done in the preterite.
When used in this way, deber is often similar to the English words “must,” “should,” and “ought.” It is sometimes easier to express obligation by using the conditional form instead of the present tense, although the difference can be hard to translate. The conditional can appear more polite when telling someone what they should do.

With a noun direct object, deber can usually be translated as “owe.” You must refer to a strong likelihood. This is often the equivalent of the English “must” when “must” isn’t used to express obligation.
There is a tendency in some areas, especially in speech, to drop the de in sentences such as those above. Nevertheless, doing so would make the sentences ambiguous and out of context. Hence, while “debias de verme” can mean only “you must have seen me,” “debias verme” can mean either “you must have seen me” or “you ought to have seen me.” In that case, you need to understand the context to make sense of what is being said.
In some regions, you may hear deber to express obligation on occasion. Nevertheless, if you are learning the language, you shouldn’t imitate this usage.
To indicate that something should have been done, deber can be used in the preterite tense, equivalent to the simple past tense in English.
