A tense is any of the forms of a verb that may be used to show the time of the action or state expressed by the verb. Thus we have two tenses in English language; Present tense and Past tense.
There is no future tense in English because there are no inflectional endings or verb forms that can signal future tense as in present and past tenses. However, we can still talk about future time in English.
Aspect is the form of a verb that shows, for example, whether the action happens once or repeatedly, is completed or still continuing. Thus we have simple aspect, perfective aspect and progressive aspect.
The form of a verb that expresses an action that is happening now or at the time of speaking. Present tense can be divided into the following aspects.
- Simple Present
- Present Progressive
- Present Perfect
- Present Perfect Progressive.
Simple present tense is used to describe the present or past tense of a verb that is formed without using an auxiliary verb. It is marked by the base form of the verb. Look at the following table.
|Base form/ infinitive form|
|– s, – es, – ies is added to the base form.|
(a) -es added to the verbs ending in the following letters; ss, sh, ch, x, o, zz. For example
|Base form||-es form|
(b) -ies is added to all verbs ending in y preceded with a consonant. ‘y’ changes into ‘i’ then –es is added.
|Base form||-ies form|
Compare the following
|Base form||-s form|
These verbs end in a ‘y’ letter but they are preceded with a vowel sound, so we simply add ‘-s’
(c) ‘-s’ is added to all the rest forms of verbs including those ending in ‘y’ preceded with a vowel.
|Base form||-s form|
Adverbs of frequency that are used with simple present
Often, always, usually, never, sometimes, occasionally, normally, seldom, rarely, constantly, frequently. These are used to describe how many times someone does something.

The form of a verb used to describe actions in the past or the time that has gone by or things that happened in an earlier time.
This is the form of the verb that describes actions that took place a long time ago. In describing or talking about past events we use the past form of the main verb without auxiliary verbs.
Auxiliary verb (to do) may be used in questions like “Did you tell him?” and in negative sentences, like “I didn’t tell him”. In both cases the –ed participle is dropped from the regular main verb and the form of irregular verb also changes. E.g. “I didn’t write that letter”.
Look at the following examples
|Positive sentences||Negative sentences||Questions|
|I loved her||I didn’t love her||Did I love her?|
|We told you||We didn’t tell you||Did we tell you?|

There are two kinds of verbs used to form simple past tense; regular and irregular verbs.
These are the verbs that form their past tense by adding –d or –ed to the verb. Most English verbs are regular.
From the list above it can be noted that;
Some verbs form their simple past by simply adding –d. these are the verbs that already end in letter –e.
some verbs form their simple past by simply adding –ed. These do not end in letter –e.
Some verbs form their simple past by simply adding –ied. These are the verbs that end in letter –y, preceded with a consonant. In this case the ‘y’ changes into ‘i’ then –ed is added.
There is an exception for the words like Fly –Flew-Flown
Simple past tense is used with some adverbs of time such as Yesterday, last night, last week, last year, ago, a long time, once upon a time, etc.
These are verbs that do not form their past tense by adding –d or –ed. The formation of past tense in irregular verbs is different from that of regular verbs.
These have no common rule to guide the formation of past tense. Although irregular verbs have a considerable variation in the way they behave in forming past tense, they can still be grouped in some groups depending on their similarities in the changes they undergo.
Those with two forms of past tense and past participle.
|Infinitive||Simple past||Past participle|
Those that do not change at all in simple past and past participle
