Add s, es, ies to a Verb to Make it Singular

When we make a sentence of present indefinite tense, we have to add a 's' sound to the end of the verb if the subject is a singular third person. 

• I read.
• We read.
• You read.
• They read.
• He reads.
• She reads.
• John reads.
• Paul reads.

The /s/ sound is formed either with an '-s', '-es' or '-ies'.  There are certain rules to put that /s/ sound there.

Let's see the s, es, ies rules -

Rules to Add -s, -es, -ies

Rule -1 : 

Add  '-s' :

Generally we use only an '-s' at the end of a verb.

 e.g. -
        Eat > eats.
        Read > reads.
        Swim > swims.
        Set > sets.
        Sleep > sleeps.
        Cut > cuts.
        Run > runs.
        Take > takes.
        Put > puts.
        Talk > talks.

Use-

I swim. > The girl swims.
We take. > She takes.
I run. > He runs.
They cut. > Rakesh cuts.

Rule 2 : 

Add '-es':

If  the verb ends with o, s, x, z, sh, ch, add '-es'.

E.g.-

Do > does,
Go > goes.

Pass > passes, 
Toss > tosses,
Mess > messes,

Bless > blesses,

Mix > mixes,

Fix > fixes,

Relax > relaxes,

Buzz > buzzes,

Fizz > fizzes,

Blitz > blitzes,

wash > washes,
Push > pushes,

Smash > smashes,

Catch > catches,
Teach > teaches,

Use-

I mix. She mixes.
I do. The man does.
We samsh. He smashes.

Rule- 3 : 

Replace -y with -ies.

 If a verb ends with -y, then replace -y with -ies.

E.g.-

• Cry > cries.
• Marry > marries.
• Carry > carries.

Use- 

You carry. She carries.
You marry. She marries.
I cry. The child cries.

Exception:-

  If a verb ends with a '-y', but there is a vowel right before that, then we have to add an ‘-s’ simply without changing anything.

E.g.-

• Lay > lays.
• Pay > pays.
• Say > says.
• Play > plays.

Use- 

I pay. He pays.
We say. Rohan says.
We play. The boy plays.
