English The Simple Present

The Simple Present is a grammatical tense that is used when we talk about something that happens always, usually or habitually. It happened in the past, it happens now, and it will probably happen in the future. To form the simple present, we use the following conjugation table.

Examples: 
I do my homework every night.
She reads books.
We like the new apartment.

When forming the simple present, we have to be mindful of the third person: For He, She, and It we always add an “s” at the end of the verb.
However, there are some spelling exceptions:

When a verb ends on –s /-ch /-sh / –x, or if the verb ends with a vowel (a, e, i, o, u) we add -es, 

Examples: 
I wash – He/She/It washes.
I miss – He/She/It misses.
I fetch – He/She/It fetches.
I fix – He/She/It fixes.
I go – He/She/It goes.

When a verb ends on consonant-y, we remove the “y” and add –ies.

Examples: 
I cry – He/She/It cries.
I try – He/She/It cries
I fly – He/She/It flies.

Note: This rule does not apply for verbs ending on vowel-y, or verbs that end on a double-vowel.
I pay – He/She/It pays. (not “paies”)
I say – He/She/It says. (not “saies”)
I see – He/She/It sees (not ‘seies”)
I sue – He/She/It sues (not “suies”)

When expressing something in the present tense negative, we use “do not – don’t”
