Here are some of the most common ways that esperar is used, with examples:
Esperar que followed by a verb: Esperar que is typically followed by a verb (although the verb may have a subject). If that verb is in the subjunctive mood, esperar can often be understood to mean "hope," while if that verb is in the indicative mood, it usually can be understood to mean "expect." (The distinction between the two isn't always precise, however, so you still need to pay attention to context.)
Note, for example, the difference in meaning between "Espero que va a ganar el torneo," which means "I expect he will win the tournament," and "Espero que ganes el torneo," "I hope you win the tournament. The use of the indicative mood (va a) in the first sentence suggests some degree of certainty, while the subjunctive mood of the second indicates desire. The use of the subjunctive following esperar que is far more common than not.
Some examples with possible translations:

Using esperar like gustar: Esperar is sometimes used in the same way as gustar and some other verbs — in a sentence with inverted word order. A usable translation in such cases often is "await":
