Classification of Verbs. Study of Verb Classification

Portuguese verbs are classified as: regular, irregular, anomalous, defective and abundant.
• Regular: are those in which the stem remains the same throughout the conjugation.
Example: verb to sing.

Cant	O	Cant	Hey
Cant	at	Cant	aste
Cant	The	Cant	or
Cant	loves	Cant	loves
Cant	oh	Cant	astes
Cant	am	Cant	plow

• Irregulars: they are verbs whose radicals change or whose endings do not follow the model of the conjugation to which they belong.
Example: verb listen.

• Anomalous: verbs that have more than one radical when conjugated.
