One of the fundamental tenses that is taught in elementary school is the simple present tense. It is used to explain habitual actions, facts, or habits and is formed by adding “-s”, “-es” or “-ies” to the verb’s base form when the subject is in the third person singular (he, she, or it).
Here are some examples:
– I have a healthy breakfast every morning.
– Tom plays basketball with her friends.
– The sun rises in the east and sets in the west.
– Rabbits eat carrots.
– I am a student.
– She has a hamster.
In these sentences, “am” and “has” are in the Present Simple tense, but they don’t follow the “add -s or -es” rule when the subject is third person singular as they are irregular verbs.
