Sentences are made up of one or more clauses. A clause consists of a subject (a noun or a pronoun) and a predicate (what is said about the noun or pronoun). The predicate contains a verb.
Adjectives or nouns used along with the verb in order to describe what is being asserted about someone or something are in the predicative position.
Nouns or pronouns which are related to (objects or receivers of) the action of the verb or related to (objects of) a preposition are called objects. There are direct and indirect objects.
The direct object of a verb is a noun or a pronoun which receives the action of the verb directly.
Some verbs take an indirect object. Indirect objects are sometimes preceded by a preposition.
Polish grammar allows subjectless sentences. Sentences which describe weather conditions, time of the day, temperature do not require subjects:
There is also a separate category of verbs, which does not have personal form. One example, past impersonal participle, is described in the chapter about the verbs. There are also other verbs, like: "widac" (it is seen), "slychac" (it is heard), "lepiej pojechac" (it is better to go), the modal verb "trzeba" (it is necessary to), and "wiadomo" (it is clear that), which do not require subjects.
