Verbs ending with "s", "ch", "sh", "x" or "z"

When a verb ends with s, ch, sh, x or z, we add the letter e, and then we add the letter s.

In the following examples the part before the letter s is in purple and the letters es are in red.

miss=>miss + es=>misses
kiss=>kiss es=>kisses
watch=>watch es=>watches
teach=>teach es=>teaches
wash=>wash es=>washes
push=>push es=>pushes
mix=>mix es=>mixes
fix=>fix es=>fixes

Verbs ending with "o"

When a verb ends with o, we add the letter e, and then we add the letter s.

In the following examples the letter o is in purple and the letters es are in red.

go=>go es=>goes
do=>do es=>does

Verbs ending with "y"

When a verb ends with y and there is a consonant before it, the y changes into ie. Then the letter s is added.

In the following examples the consonant is in blue, the part before the letter s is in green, and the letter s is in red.

fly=>flie + s=>flies
try=>trie + s=>tries
cry=>crie + s=>cries
study=>studie + s=>studies

When a verb ends with y, and there is a vowel before it, we simply add the letter s to the verb.

In the following examples the vowel is in orange, the part before the letter sis in green, and the letter s is in red.

buy=>buy s=>buys
say=>say s=>says
pay=>pay s=>pays
play=>play s=>plays
enjoy=>enjoy s=>enjoys



So these were the spelling rules for adding "s" in the Simple Present.

Spelling the - S Form

English verbs have five basic forms: the base form, the - S form,
the - ing form, the past form, and the past participle form.

The - S form is very commonly used for main verbs and auxiliary
verbs in the 
simple present tense when the subject is or means
heshe, or it. The - S form is also very commonly used as a full
(has) or contracted ('s) auxiliary verb in the 
present perfect tense
when the subject is or means heshe, or it.

For be, the - S form is is. For have, it is has. For other verbs,
there are three different spellings: - 
s, - es, and - ies:

1.

Add - s to the base form.

This is the most common spelling for the -S form and
is the spelling used for most verbs.

Notice, especially, that - s is added when the base form
ends in one or more consonants + e:

aches, bakes, breathes, cares, caches, dives,
edge
s, fiddles, files, glares, hates, hopes, jokes,
live
s, makes, notes, pastes, races, spares, surprises,
taste
s, types, writes

Notice that - s is also added when the base form ends
in one or more consonants (but without e):

adds, bets, beats, calls, claps, cheats, cleans, digs,
drop
s, eats, fills, finds, fits, gets, grabs, hops, kills,
knit
s, links, lists, means, needs, opens, puts, quits,
rob
s, rings, rips, sends, stops, tells, trusts, voids,
want
s, works, zips

In addition, notice this spelling is used with the small
number of verbs ending in two vowels (including 
- ie):

agrees, argues, boos, coos, flees, glues, moos,
see
s, shoos, shoes, tees, woos

dies, lies, ties, vies

2.

Add - es to the base form.

This happens in two situations:

a.

when the base form ends in the vowel o:

does, goes, soloes

b.

when the base form ends in sssh,
(t)chzz, and x:

assesses, blesses, caresses, fusses,
kiss
es, misses, passes, tosses;

blushes, dashes, flashes, gnashes,
hush
es, lashes, mashes, pushes, rushes,
splash
es, stashes, washes, wishes;

catches, ditches, etches, flinches,
hitch
es, itches, marches, mooches,
patch
es, reaches, searches,
scratch
es, teaches, touches, watches;

buzzes, fizzes;

boxes, coaxes, faxes, fixes,
relax
es, vexes, waxes.

3.

Change y to i and add - es.

This happens when a verb ends in a consonant y:

apply / applies; bury / buries
carry / carr
ies; copy / copies; cry / cries;
dry / dr
ies; fly / flies; fry / fries;
hurry / hurr
ies; marry / marries; pity / pities;
ply / pl
ies; pry / pries; tidy / tidies; try / tries;
worry / worr
ies.

Verbs that end in a vowel y do not change the y
to i and then add - es, however:

buy / buys; employs / employs; enjoy / enjoys;
flay / flay
s; lay / lays; pay / pays; play / plays;
say / say
s; slay / slays; spray / sprays; stay / stays;
sway / sway
s;

Important:

Compare flay / flays, play / plays, and pray / prays
with fly / fl
ies, ply / plies, and pry / pries to see
how these spelling rules work for verbs ending in 
s.
