Third person singular
We add –s to the verb to form the third person singular (he, she, it).
I drink – he drinks
I run – he runs
But
We add –es to verbs that end in –ss,
-sh, -ch, -x, -o.
I watch – he watches
With verbs ending in consonant + y,
we change the –y to –ies.
I cry – he cries
But with verbs ending in vowel + y,
we just add –s as usual.
I play – he plays
We use the Present Simple:
for habits and actions that we do regularly:
He visits his friends every Sunday.
She goes to school by bus.
for general truths:
The sun rises in the East.
for permanent situations:
He lives in Athens.
