Tomatoes or Tomatos: Which Spelling Is Correct?

Quick Answer

The correct plural spelling is tomatoes.

Tomatos is incorrect in standard English. The singular noun is tomato, and its plural form is tomatoes.

• One tomato
• Two tomatoes
• A basket of tomatoes
• The tomatoes are ripe.

The spelling changes from tomato → tomatoes because tomato is one of the English nouns ending in -o that traditionally forms its plural with -es, rather than simply adding -s.

Correct Forms Table

Form	Correct?	Explanation	Example
tomato	✓	Singular noun	I sliced one tomato.
tomatoes	✓	Standard plural form	The tomatoes are fresh.
tomato’s	✓	Singular possessive	The tomato’s skin was wrinkled.
tomatoes’	✓	Plural possessive	The tomatoes’ leaves were damaged.
tomatos	✗	Nonstandard spelling/typo	Not the standard plural of tomato.
tomatoe	✗	Incorrect spelling	Tomatoe is not the standard spelling.
tomatoed	Possible	Verb form of the uncommon verb tomato, when that verb is intended	The dish was tomatoed with a rich sauce.

So, if you are asking “is it tomatoes or tomatos?”, choose tomatoes.

If you are asking “tomatoes or tomato’s?”, choose tomatoes for the plural. Tomato’s has an apostrophe because it is a possessive form, not an ordinary plural.

Why Is It Tomatoes Instead of Tomatos?

The word tomato ends in -o, and English has several nouns ending in -o whose plurals traditionally take -es.

For tomato, the pattern is:

tomato + es = tomatoes

The final o remains, and -es is added:

tomato → tomatoes

This is an example of inflection, specifically plural formation. The noun does not change into a completely different word; its grammatical form changes to indicate more than one tomato.

The same general pattern appears in words such as:

• potato → potatoes
• echo → echoes
• hero → heroes
• torpedo → torpedoes

However, there is an important point: English does not have one universal rule saying every noun ending in -o must take -es. Other nouns use -s, including photo → photos, piano → pianos, and radio → radios.

That is why it is better to learn the established plural form of each word rather than apply an absolute “-o always becomes -oes” rule.

The Plural of Tomato Is Tomatoes

The tomatoes plural form is tomatoes.

If someone asks “What is the plural of tomato?”, the answer is:

tomato → tomatoes

The plural spelling of tomato is not tomatos. The letters e and s are both required.

This applies whether you are writing about food, gardening, agriculture, cooking, or everyday conversation:

• Fresh tomatoes taste excellent in salads.
• She bought six tomatoes at the market.
• The garden produced dozens of tomatoes this year.
• Cut the tomatoes into small pieces.
• These tomatoes are ready to harvest.

There is no difference between British and American English in this plural spelling. Tomatoes is the standard form in both major varieties of English.

Tomatoes vs. Tomatos: The Spelling Pattern

The easiest way to understand tomatoes vs. tomatos is to look at the word ending.

Incorrect:

tomato + s → tomatos

Correct:

tomato + es → tomatoes

The additional e is part of the plural ending in the established spelling.

This is not simply a pronunciation trick. The spelling must be learned as part of the word’s morphology. When tomato functions as a plural noun, standard English spells the form tomatoes.

How Do You Spell Tomato?

The singular word is spelled:

tomato

It contains the sequence tom-a-to:

T-O-M-A-T-O

The plural is:

tomatoes

Spelled:

T-O-M-A-T-O-E-S

A common mistake is adding an unnecessary e before the final plural ending in the wrong place, producing tomatoe, or adding only s, producing tomatos.

So if you are wondering “how do you spell tomato?”, the singular is tomato. If you are wondering “how do you spell tomatoes?”, the plural is tomatoes.

Examples of Tomato in Singular and Plural Forms

Seeing the forms in natural sentences makes the distinction easier to remember.

Singular: Tomato

Use tomato when referring to one item:

• I need one tomato for the recipe.
• That tomato is perfectly ripe.
• She planted a tomato in a large pot.
• He cut the tomato into slices.
• The chef selected a fresh tomato.

Plural: Tomatoes

Use tomatoes when referring to two or more:

• I bought five tomatoes.
• The tomatoes are growing quickly.
• We used fresh tomatoes in the sauce.
• The market sells locally grown tomatoes.
• Several tomatoes were still green.

The basic contrast is therefore straightforward:

one tomato → several tomatoes

In Questions

The same distinction works in questions:

• How many tomatoes do we need?
• Did you buy a tomato?
• Which tomatoes should I use?
• Is that a tomato or another type of fruit?

Tomato’s, Tomatoes, and Tomatoes’

Apostrophes cause a separate type of confusion.

Tomatoes is the ordinary plural:

We bought three tomatoes.

Tomato’s is normally the singular possessive:

The tomato’s color changed overnight.

Here, the apostrophe shows that something belongs to or is associated with one tomato.

Tomatoes’ is the plural possessive:

The tomatoes’ skins were beginning to wrinkle.

This distinction matters because tomato’s is not an alternative spelling of the plural.

So:

• tomato = one
• tomatoes = more than one
• tomato’s = belonging to one tomato
• tomatoes’ = belonging to multiple tomatoes

If you are deciding between tomatoes or tomato’s when you simply mean more than one, the correct choice is tomatoes.

Is Tomatoe a Word?

In standard modern English, tomatoe is not the correct spelling of the noun.

The standard singular form is tomato, without a final e.

Therefore:

• tomato ✓
• tomatoe ✗
• tomatoes ✓
• tomatos ✗

The mistake is understandable because English contains many words ending in -oe or words whose spelling patterns may make a final e seem plausible. But tomato does not have that spelling.

Common Mistakes With Tomatoes

Writing Tomatos

Tomatos is the most direct plural-spelling error.

✗ I bought four tomatos.
✓ I bought four tomatoes.

The missing e is the key error.

Writing Tomatoe

Some writers mistakenly add an e to the singular:

✗ I sliced a tomatoe.
✓ I sliced a tomato.

The e appears in the plural tomatoes, but not in the singular tomato.

Using Tomato’s as the Plural

An apostrophe should not normally be used to create an ordinary plural.

✗ We grow tomato’s.
✓ We grow tomatoes.

The apostrophe changes the grammatical function of the word.

Confusing Tomato and Tomatoes

A singular count noun generally needs a determiner when used in ordinary prose:

✓ I ate a tomato.
✓ I ate three tomatoes.

Not:

✗ I ate three tomato.

The number determines whether the noun should be singular or plural.

Using Tomattos or Tamados

Tomattos and tamados are not standard spellings of the word. They are best treated as misspellings or typing errors.

The correct spelling remains:

tomato → tomatoes

Is Tomatoes a Regular Plural?

Tomatoes is a regular plural in the sense that it is formed through ordinary English plural inflection rather than being an irregular form such as child → children or mouse → mice.

However, it is not formed by simply attaching -s. It uses the established -es plural spelling:

tomato + -es → tomatoes

This is why calling tomatoes an “irregular plural” can be misleading. It is better understood as a regular English plural with a particular spelling pattern associated with this class of nouns.

British and American English

There is no meaningful British-versus-American spelling difference here.

Both British English and American English use:

tomato → tomatoes

The pronunciation of tomato does differ between the two varieties. British English commonly uses a pronunciation with a broad /ɑː/ vowel in the final syllable, while American English commonly uses a different vowel quality. The spelling of the plural, however, remains tomatoes.

So you do not need to choose between tomatoes and tomatos based on your country or variety of English.

Tomato and Potato: Why Both Become Tomatoes and Potatoes

A useful memory aid is the familiar pair:

tomato → tomatoes
potato → potatoes

Both nouns end in -o and take -es in their standard plural forms.

This is why the phrase “plural of tomato and potato” is easy to remember as a pair:

• one tomato → two tomatoes
• one potato → two potatoes

But don’t extend this to every noun ending in -o. English has many established exceptions:

• photo → photos
• piano → pianos
• radio → radios
• video → videos

The safest lesson is therefore not “every -o word takes -es.” The transferable lesson is that English plural formation for nouns ending in -o varies by word, so established usage determines the standard form.

What About Tomatoed?

Tomatoed can occur when tomato is being used as a verb, but this is much less common than the noun tomato and its plural tomatoes.

English sometimes converts nouns into verbs, and when a verb is formed from tomato, the regular past-tense ending -ed can produce tomatoed.

For example, in a specialized or playful context, a writer might say:

The vegetables were tomatoed with a rich sauce.

However, this is not a form most readers need in ordinary English. In normal food writing, it is usually clearer to use a more established verb such as added tomatoes, covered with tomato sauce, or topped with tomatoes.

The existence of tomatoed does not affect the spelling of the noun’s plural: tomatoes remains correct.

How to Remember the Spelling

Use this simple two-step memory pattern:

One tomato
Two tomatoes

Think of the plural as tomato + ES.

A particularly useful mnemonic is:

Tomatoes grow with an E.

You can also pair it with potato:

tomato → tomatoes
potato → potatoes

Then remember that other -o words may behave differently:

photo → photos

This prevents the common mistake of turning the memory aid into a false universal rule.
