In English we often say things like “I like tomatoes.” To express the same idea in Russian we use the verb нравиться/понравиться, but the verb does not mean ‘like’. Before we discuss its usage, let's look at its conjugation. Note that it is a reflexive verb:

Нравиться literally means “to please/be pleasing,” so to communicate the ‘like’ idea, you have to mentally rephrase “I like tomatoes” as “Tomatoes please me”. Notice this is grammatically quite different than the analogous English sentence. In English the person experiencing the pleasure is the subject of the sentence, and the source of the pleasure is the direct object:

In Russian the source of the pleasure is the subject of the sentence, which means it appears in the nominative case. The verb, of course, agrees with the subject. The person experiencing the pleasure is the indirect object and appears in the dative case:

Thus when one person likes another, we can have sentences like these:

There is one last quirk. In the Russian sentence, the source of pleasure often (though not always) shows up in final position, just as in the English sentence, even though grammatically it is the subject. Notice that the verb agrees with the subject in the Russian sentence, even though the subject is at the end of the sentence:

Here are some present tense sentences. Notice carefully the case of each subject and object, and how the verb agrees with the subject:

Now let's look at those same sentences in the past tense. Note how the verb agrees with the subject:
