The Principal Parts of Verbs

Every verb can take different forms to show when the verb’s action or state of being happened. The main forms of a verb are called its principal parts.

The principal parts of a verb are the base form, the present participle, the past, and the past participle. All other verb forms are formed from these principal parts.

In the following chart, all helping verbs are shown in brackets because present participles and past participles cannot be used as verbs unless accompanied by helping verbs.

BASE FORM	PRESENT PARTICIPLE	PAST	PAST PARTICIPLE
trick	[is] tricking	tricked	[have] tricked
marry	[is] marrying	married	[have] married
go	[is] going	went	[have] gone

Regular Verbs

All verbs form the present participle by adding –ing to the base form.

BASE FORM	PRESENT PARTICIPLE
spray	[is] spraying
organize	[is] organizing
swing	[is] swinging

A regular verb forms its past and past participle by adding –d or –ed to its base form.

BASE FORM	PAST	PAST PARTICIPLE
prepare	prepared	[have] prepared
follow	followed	[have] followed

REMINDER

Do not leave off the –d or –ed from the past or past participle forms of a regular verb.

Irregular Verbs

An irregular verb forms its past and past participle in some way other than by adding –d or –ed to its base form.

Irregular verbs form their past and past participle forms in one of the following ways:

1. changing vowels 
2. changing vowels and consonants 
3. changing consonants 
4. making no change

BASE FORM	PAST	PAST PARTICIPLE
win	won	[have] won [The i in win changes to o.]
build	built	[have] built [The d in build changes to t.]
do	did	[have] done [Vowels and consonants in do change.]
spread	spread	[have] spread [There is no change to spread.]

REMINDER

All verbs form the present participle by adding –ing to the base form of the verb.

• begin 
• forsake

   Todd broke your record. 
2. Using the past participle of a verb without a helping verb
