Verbs may change in shape for the PRESENT, PAST, or FUTURE, and not all are regular in this. Most dictionaries have lists of irregular verbs, to show the first, second, and third form, for verb base or infinitive shapes.
AN IRREGULAR VERB
The infinitive: to ring;
The base form: ring.
FIRST FORM
1ST
ring
SECOND FORM
2ND
rang
THIRD FORM
3RD
rung
Regular verbs take the ending –ED, in their second and third forms.
A REGULAR VERB
The infinitive: to sound;
The base form: sound.
FIRST FORM
1ST
sound
SECOND FORM
2ND
sounded
THIRD FORM
3RD
sounded
A brief note on basic and infinitive shapes of verbs can help us work with grammar resources. We build the infinitive with the basic form of the verb and the particle “to”.
BASE FORM: ring
THE INFINITIVE: to ring.
In English, the base form is usually the first form too.
I will write home tomorrow, the FUTURE field of time;
(“write” is the first and the basic form of the verb to write).

For the verb to be, the base form is different from the first form.
I will be home tomorrow, the FUTURE field of time (“be” is the base form of the verb to be; the first forms are am, is, are).
We can see these first forms in our PRESENT field of time.

The particle “to” does not belong with the infinitive only. To tell the difference, we mind if the particle comes with a verb or a noun. The infinitive is a verb form.
I like to listen to music;
(the infinitive particle is underlined).
I often listen to music;
(there is no infinitive here, music is a noun, that is, a word that can answer the question, Who or what?)
■APPENDIX 1 tells more about verbs. ■APPENDIX 2 and ■APPENDIX 3 show verb speech sound patterns. Irregular verbs are easier to learn with these language melodies.

Exercise 5. Let us put the verbs in forms proper for the indicated grammatical time.
In simple words again, let us put the verbs in the fields of time. We work as in the ■MIND PRACTICE.
The speech sound pattern here is
I: ― e: ― e:
FIRST FORM
1ST
leave
SECOND FORM
2ND
left
THIRD FORM
3RD
left
Example: PAST (leave);
Answer: left.
1. FUTURE (leave);
2. PRESENT (mean);
3. PRESENT (meet);
4. PAST (read);
5. FUTURE (sleep);
6. PAST (sweep);
7. PAST (sleep);
8. PRESENT (read);
9. FUTURE (meet);
10. PRESENT (sweep).
Exercise 6. Another way round, we tell the field of time by the shape of the verb. We show pronunciation — that is, the way to say a word — in brackets.
Example: left;
Answer: (time first) PAST (leave).
1. meet(s); 2. read {re: d}; 3. read {rI: d}; 4. will sleep; 5. will leave; 6. met; 7. mean(s); 8. meant; 9. slept; 10. swept.

Chapter 3. Time is like a river: verb patterns
Everyday language has phrases as a flow of time, a course of events: we people happen to have such impressions about life. Grammatical patterns for words and time may look a lot to think about at first, and this is why we begin with a good glimpse. ■More
