principal part
Verb's key inflections
Principal parts are the core forms of a verb from which all other forms can be derived.
In English, verbs typically have four principal parts: the base form (sing), the past tense (sang), the past participle (sung), and the present participle (singing).
Learning these forms is essential because irregular verbs don't follow predictable patterns: The principal parts of "go" are go, went, gone, going.
