Spanish Grammar - Hay, Hubo Spanish grammar lesson 10: How to say there is, there are, there was, and there were The verb haber is a very important auxilliary verb, meaning, to have, used with a past participle, as in, for example, He has gone, El ha ido. (This is of course not to be confused with the regular transitve verb, tener, which means to have.) But haber also has another meaning. It is the impersonal verb that means to be, used in a specific way, as in, for example, there is snow, Hay nieve. Notice that in the second example above, the word hay is used, (not ha). It is a special conjugation, used when haber is in its to be form in the present tense.
