In Spanish, the progressive forms are made by using a conjugation of estar followed by the gerund (-ando or -iendo verb form). The progressive forms are used less often in Spanish than in English, and many thoughts that are expressed in English using progressive verb forms are not properly translated that way into Spanish. In Spanish, the progressive verb forms often emphasize the continuing nature of the verb's action.
In Spanish grammar, progressive verb forms can also refer to the use of verbs other than estar that are combined with gerunds. For example, the gerund can be combined with the verb andar, as in this sentence: Andaba hablando de cambio de actitud. (He went about talking about a change of attitude.)
