In Polish grammar, the infinitive is a basic form of the verb that usually ends with the suffixes “-ฤ” or “-c” (for example, “czytaฤ”, “mรณwiฤ”, “jeลฤ”, “piฤ”). In English, this corresponds to the base form of the verb, like “read”, “speak”, “eat”, “drink”. It is used in Polish in several contexts, such as after certain verbs and expressions or to express a purpose. Infinitives play a key part in understanding and mastering Polish grammar.
