|The INFINITIVE form of a verb
is the form which follows to:
This form is indistinguishable from the base form.
Indeed, many people cite this form when they identify a verb, as in "This
is the verb to be", although to is not part of the verb.
to are referred to specifically as TO-INFINITIVES, in order to
distinguish them from BARE INFINITIVES, in which to is absent:
|Help me to open the gate
||Help me open the gate
So far we have looked at three verb forms:
the present form, the past form, and the infinitive/base form. Verbs have
two further forms which we will look at now.
Verb Forms: -ing and -ed
The verb form writing in  is known
as the -ing form, or the -ING PARTICIPLE form. In , the
verb form produced is called the -ed form, or -ED
 The old lady is writing
 The film was produced
Many so-called -ed participle forms
do not end in -ed at all:
All of these forms are called -ed participle
forms, despite their various endings. The term "-ed participle form"
is simply a cover term for all of these forms.
The film was written
by John Brown
The film was bought
by a British company
The film was made
The -ed participle form should not
be confused with the -ed inflection which is used to indicate the
past tense of many verbs.
We have now looked at all
five verb forms. By way of summary, let us bring them together and see
how they look for different verbs. For convenience, we will illustrate
only the third person singular forms (the forms which agree with he/she/it)
of each verb. Notice that some verbs have irregular past forms and -ed
