Verbs can be classified into several types based on their meaning and grammatical function. The main types are:
1. Physical verbs describe actions like run, hear, call that involve physical movement or senses.
2. Mental verbs refer to cognitive states like know, recognize, believe.
3. State of being/linking verbs connect subjects to complements and describe states like be, seem, become.
4. Verbs are also classified based on their valency or number of arguments, including intransitive, transitive, ditransitive, double transitive and ambitransitive verbs. Copular verbs and auxiliary verbs have special grammatical functions.
