Verb Forms and Verb Tenses (#1)

Overview

English verbs have five basic forms: the base form, the - S form,
the - ing form, the past form, and the past participle form:

1.

the base (or simpleform

For all verbs except BE, the base form is the
verb with "no special ending" (no - s- ing,
- ed, etc.).

2.

the - S (or third-person singular,
present tenseform

For BE, this form is is and for have, it's has.
For other verbs, the - S form is the verb + - s or

- es.

Note: For some verbs enging in yy --> - i + es.

3.

the - ing (or present participleform

For many verbs, this form is the verb + - ing.
For some verbs, the last consonant must be
doubled in order to form the -ing form correctly.
For verbs which end in a consonant + -e,
the -e is dropped.

4.

the past form

For many verbs (regular verbs), this form
is the verb + - d or - ed; for some verbs ending
in 
yy --> i + ed.

For many other verbs (irregular verbs), the past
form may resemble the base form with "internal
changes" (for example, do / didtook / take;
see / saw) or be the same as the base form
(for example, cut / cutcost / costput / put).
In a few cases, the past form may look quite
different from the base form (for example,
go / went and buy / bought).

5.

the past participle form

For regular verbs, this form is the same as the
past form. For irregular verbs, this form often
has "internal changes" (for example, do / did / 
done;
go / went / 
gonesee / saw seen), but the past
participle may be the same as the base form and / or
the past form (for example, cost / cost / 
cost;
set / set / 
setpay / paid / paidsell / sold / sold).
