Simple present
The simple present, also known as the present simple or present indefinite, is a verb tense in English grammar used to express habits, general truths, repeated actions, and states that are generally true in the present. It is the most basic way to refer to actions or situations in the present time.[1]Formation
Affirmative
The affirmative form of the simple present tense in English is used to express facts, habits, or general truths in declarative statements. It consists of the subject followed by the base form of the main verb, with a specific modification for third-person singular subjects. This structure applies to all persons except the third-person singular, where an ending is added to the verb.[2] For subjects in the first person (I, we), second person (you), and third person plural (they), the affirmative construction uses the subject plus the plain base form of the verb without any inflection. For example, "I walk to work every day" or "They play football on weekends." In the third-person singular (he, she, it, or singular nouns), the base form of the verb is modified by adding -s or -es to indicate agreement with the subject. Most regular verbs simply add -s, as in "She walks to work" or "The bus leaves at 8 AM." Verbs ending in -s, -sh, -ch, -x, -z, or -o take -es instead, such as "He watches TV" (from watch) or "She goes to the market" (from go). If a verb ends in a consonant followed by -y, the -y changes to -ies, for example, "The baby cries at night" (from cry). These rules ensure morphological consistency in the tense.[3] The pronunciation of the -s or -es ending in third-person singular varies based on the preceding sounds for clarity in spoken English. It is pronounced as /s/ after voiceless consonants (e.g., /k/, /p/, /t/), as in "He likes coffee" (/laɪks/). After voiced sounds (e.g., vowels or /b/, /d/, /g/), it is /z/, such as "She reads books" (/riːdz/). For sibilants (e.g., /s/, /ʃ/, /tʃ/, /z/, /ʒ/, /dʒ/), it becomes /ɪz/, for instance, "The cat watches birds" (/wɒtʃɪz/). These phonetic adjustments follow standard English phonology rules.[4]Negative
The negative form of the simple present tense is formed using the auxiliary verb "do" or "does" followed by "not" and the base form of the main verb. For first person singular and plural (I, we), second person (you), and third person plural (they), use "do not" (contracted as "don't") + base form. For third-person singular (he, she, it), use "does not" (contracted as "doesn't") + base form. Examples include: "I do not (don't) like coffee" and "She does not (doesn't) work here." This structure applies to most main verbs; the verb "to be" forms negatives differently (e.g., "I am not").[1][2]Interrogative
The interrogative form of the simple present tense for yes/no questions uses "do" or "does" + subject + base form of the main verb. For I, you, we, they, use "Do" + subject + base form (e.g., "Do you play tennis?"). For third-person singular (he, she, it), use "Does" + subject + base form (e.g., "Does he live here?"). Contractions are not typically used in questions, though short answers may use them (e.g., "Yes, I do."). For wh-questions, a question word precedes the auxiliary (e.g., "Where do they go?"). As with negatives, this applies to most main verbs; "to be" uses inversion (e.g., "Are you happy?").[1][2]Conjugation
Regular verbs
Regular verbs in the simple present tense follow a predictable pattern of conjugation based on the subject pronoun or noun phrase. For first person singular (I), second person singular and plural (you), first person plural (we), and third person plural (they), the base form of the verb is used without any inflection. In contrast, for third person singular subjects (he, she, it, or a singular noun), the verb takes an ending of -s or -es. This distinction applies universally to regular verbs, which are those that form their past tense by adding -ed (or -d) to the base, excluding modal auxiliaries like can or must that do not inflect in the present tense.[5][1] The full conjugation paradigm for a regular verb such as "walk" is illustrated below:| Pronoun | Conjugation |
|---|---|
| I | walk |
| you (singular) | walk |
| he/she/it | walks |
| we | walk |
| you (plural) | walk |
| they | walk |
Irregular verbs
In the simple present tense, most irregular verbs conjugate similarly to regular verbs by adding -s or -es to the base form for third-person singular subjects (he, she, it), with deviations occurring only in a small number of high-frequency verbs.[9] These exceptions deviate from the standard pattern through stem changes, unique forms, or lack of inflection altogether, making them essential for accurate usage.[10] The verb to be stands out as completely irregular in the simple present, with distinct forms for different subjects: am for I, are for you/we/they, and is for he/she/it. For example, "I am happy," but "She is happy." Similarly, to have uses have for most subjects but has in the third person singular, as in "I have a book" versus "He has a book."[10] The verb to do follows suit, changing to does for he/she/it, for instance, "We do exercises" but "She does exercises."[10] Another common example is to go, which becomes goes in the third person singular due to a spelling adjustment, as in "They go home" versus "It goes home."[11] Modal auxiliary verbs represent another category of irregularity, as they do not inflect for person or number in the simple present and remain in their base form across all subjects, without adding -s.[12] Common modals include can, may, will, shall, must, could, might, should, would, and ought to. For example, "I can swim" and "He can swim" use the same form.[13] The following table summarizes the simple present conjugation for these key irregular verbs:| Base form | I/you/we/they | He/she/it | Example (affirmative) |
|---|---|---|---|
| be | am / are | is | I am / She is a teacher. |
| have | have | has | We have time / It has ended. |
| do | do | does | You do well / He does well. |
| go | go | goes | They go early / She goes early. |
- Can: I can / He can
- May: You may / She may
- Will: We will / It will
- Shall: They shall / He shall
- Must: I must / She must
- Could: You could / It could
- Might: We might / He might
- Should: They should / She should
- Would: I would / He would
