This impersonal verb is always used in the third person singular, but may be inflected in tense (such as present or past) and mood (such as indicative or conditional). The 'subject' of the verb is inflected in the adessive case. To see the conjugated forms of the verb, see olla.
pulla is normally in the accusative case (which appears as either the nominative or genitive case depending on the context), but is inflected in the partitive case to express an ongoing or incomplete action or if used in the negative.
