Regular verbs are an important part of language, and luckily, they’re relatively easy to learn.

There are thousands of regular verbs in English! Each of them behaves the same way

you add “-ed” or “-d” to the end of the verb.

A participle is a non-finite verb that can also be used as an adjective.

For example:

·        He looked at his burned finger.

·        He has burned his finger.

In the first sentence, the word “burned” is being used as an adjective. In the second, it is used as the past participle.

The past participle of a verb is always used with the verb “to have” (“He has burned his finger”). It is most often used to form the past perfect tense, to describe an action that has already been completed.

Here are some more examples of past participle regular verbs:

·        I have completed my homework.

·        We had talked about it.

·        They had played in the garden.

The great thing about regular verbs is that they don’t change their form at all between the simple past tense and the past participle. You still form them simply by adding “-ed” or “-d” to the end of the regular verb.

Irregular verbs are one of the hardest parts of the modern English language because they’re all a little different. Since there’s no formula, English speakers have no choice but to memorize each one, along with their special verb forms.

Irregular verbs do not follow the usual rules of grammar for the tense and past participle. Irregular verbs have their own unique tense forms and past participle. For irregular verbs, you have to change the inside vowel of a verb in most cases. For example, 'swim' changes to 'swam' and 'swum

Even if a verb is irregular, the present participle is still formed by adding -ing to the end of the base—no exceptions there are no irregular present participles in the English language. Sometimes you may have to tweak the spelling a little, but the ending will always be -ing.

Irregular Past Tense and Past Participles

·        They all have one important characteristic in common: they almost never end in -ed. Some examples are ate, fought, swam, and given.

·        It's very common for a vowel (or pair of vowels) to be different from the base form. Began (base form, begin) and froze (base form, freeze) are a two good examples.

·        Most irregular verbs follow a specific pattern. You'll learn more about this concept later in this lesson.

Past Tense

With the irregular past tense, it is common for a vowel in the middle of the verb to change instead of the verb's ending. The verb drive, for example, changes to drove in the past tense.

Other verbs require you to change a vowel and add a new ending. Eat, for example, turns into ate in the past tense.

One of the most common irregular past tense endings is -t (sweep → swept). Sometimes you'll add -d (sell → sold) or -ght (catch → caught) instead.

Often, when the base ends in -ck, -e, -g, -ght, or -n, the past tense will keep that final letter or set of letters.

stick → stuck
drive → drove
ring → rang
fight → fought
run → ran

Past Participles

 irregular past participles can be formed by changing a vowel, adding a new ending, or doing both. However, the vowel or ending is often (but not always) different from the past tense form. For example, many irregular past participles require you to add an -en, -n, or -ne ending (drive → driven).

Many irregular past participles end in -en, but, similarly to the past tense, they can also end in -t, -ck, -d, -e, -g, or -ght.

 Pay special attention to the vowel changes and different endings.

Present Tense: Irregular Third Person Singular

Verbs that are irregular in the present tense are almost always irregular only in the third person singular form (he, she, it). There are very few verbs that fall into this category; they are to have, to do, and to go.

How to Make an Affirmative Sentence?

Forming an affirmative sentence is a simple task. All that you need to do is to see to it that the statement is positive. An affirmative sentence can be a declarative or assertive sentence, and it can be either a simple, complex or compound sentence as long as it is positive.

·        Tokyo is the capital of Japan.

·        My phone has two displays.

·        The teacher gave us our marksheets

A negative sentence is a sentence that states that something is false. In English, we create negative sentences by adding the word 'not' after the auxiliary, or helping, verb. An example of an auxiliary verb is the helping verb 'be.

1.     I am not going to the grocery store today./I'm not going to the grocery store today.

2.     It is not cold outside today. /It isn't cold outside today.

The basic function of an interrogative sentence is to ask a direct question. It asks us something or requests information (as opposed to a statement which tells us something or gives information). Interrogative sentences require an answer. Look at these examples:

·        Is snow white? (answer → Yes.)

·        Why did John arrive late? (answer → Because the traffic was bad.)

This task currently helps me a lot in my work since I have many English-speaking clients, so learning the regular and irregular verbs in the perfect tenses and the subject verb agreement helps my ideas to be understood by clients. Now I can put into practice the rules I learned and review them day by day to improve my English. In addition, I also learned a lot about how to form the different forms of affirmative, negative and interrogative sentences. Now it is up to me to put into practice every day  what I have learned so I don't forget these rules.

‘I am happy.’

‘You’re late!’

‘She’s brilliant.’

‘Are they all here?’

If we want to use ‘to be’ in its negative form, we add ‘not’ (or the abbreviation ‘-n’t’) to the verb, like this:

‘I’m not hungry.’

‘He isn’t here at the moment.’

‘They aren’t ready.’

We can also use the verb ‘to be’ in its infinitive form, usually when we’re giving advice or commands, such as ‘be good’, ‘be kind’ or ‘be yourself’. Additionally, we use the infinitive form when the verb ‘to be’ is accompanied by a modal verb (‘We should be there’).

"Her house was built in 1987."

‘I was on holiday.’

‘Weren’t you at the party?’

Some verbs have irregular past tenses. For example; Hannah told him about her holiday. We do not add "d" or "ed" to the irregular past tense verb but change the spelling. Tell becomes told not told.

We also make the past tense by using the verb "to be" and add "ing" word.
