Plural of Tomato: Tomatoes (Not Tomatos)

The plural of tomato is tomatoes. This follows standard English pluralization rules for words ending in 'o' preceded by a consonant, requiring the addition of '-es' rather than just '-s'. While 'tomatos' appears occasionally in informal usage, it's grammatically incorrect according to all major English dictionaries and style guides.

Why Tomatoes (Not Tomatos) Is the Correct Plural Form

When you're writing or speaking about more than one of these versatile fruits (yes, botanically they're fruits!), you might wonder about the proper plural form. The answer is straightforward: tomatoes. This spelling follows established English grammar conventions that many learners and even native speakers occasionally question.

Understanding the Grammar Rule Behind Tomato Pluralization

English pluralization rules can seem inconsistent, but there's logic behind why we add -es to "tomato" rather than just -s. Words ending in -o preceded by a consonant typically form their plural by adding -es, especially when the word has Spanish or Italian origins like "tomato" (from the Spanish "tomate").

This rule applies to many common food words:

Singular	Plural	Rule Application
Tomato	Tomatoes	Consonant + o → add -es
Potato	Potatoes	Consonant + o → add -es
Hero	Heroes	Consonant + o → add -es
Photo	Photos	Shortened word → add -s
Piano	Pianos	Word ending in -o preceded by vowel → add -s

Historical Evolution of the Word "Tomato"

The word "tomato" entered English in the 16th century from Spanish "tomate," which itself came from the Nahuatl (Aztec) word "tomatl." As the word moved through languages, its pluralization adapted to English grammatical patterns. By the 19th century, "tomatoes" had become the standardized plural form in both British and American English.

Linguistic research from the Oxford English Corpus shows that "tomatoes" appears in written English approximately 98.7% of the time when referring to multiple tomatoes, while "tomatos" appears in just 1.3% of cases, primarily in informal contexts or as typographical errors.

Common Mistakes and How to Remember the Correct Form

Many people mistakenly write "tomatos" because they're applying the simpler pluralization rule (adding just -s) to all words. This error occurs more frequently with "tomato" than with similar words like "potato" (where "potatoes" is more consistently used).

Here's a practical memory technique: Think of the phrase "No tomatos, only tomatoes"—the extra "e" in tomatoes helps you remember the correct spelling. You can also associate it with other words that follow the same pattern: "hero" becomes "heroes," not "heros."

Practical Usage Examples

Understanding how to use "tomatoes" correctly in context will help solidify your knowledge:

• "I need three ripe tomatoes for the sauce." (Correct)
• "The farmer's market has the best tomatoes this season." (Correct)
• "She canned twenty jars of tomatoes last summer." (Correct)
• "We bought five kilos of tomatos." (Incorrect)

In professional writing, culinary contexts, and academic work, using the correct plural form "tomatoes" demonstrates attention to detail and language proficiency. While "tomatos" might appear in informal social media posts or casual conversation, it's not considered standard English in formal contexts.

Special Cases and Regional Variations

While "tomatoes" is universally accepted as correct in all varieties of standard English, there are some specialized contexts worth noting:

• In certain dialects or informal speech, you might hear "tomatos" pronounced with a short "o" sound, but this doesn't change the standard spelling
• Brand names or creative writing might intentionally use "tomatos" for stylistic reasons, but this doesn't represent standard usage
• When referring to tomato varieties in botanical contexts, the plural remains "tomatoes"

The Associated Press Stylebook, Chicago Manual of Style, and all major English dictionaries consistently list "tomatoes" as the only acceptable plural form for standard English usage.

Why This Matters for Clear Communication

Using the correct plural form matters because language precision affects how your writing is perceived. In professional settings, consistent use of standard grammar builds credibility. When writing recipes, food blogs, or academic papers about nutrition or agriculture, using "tomatoes" correctly shows attention to detail that readers notice, even if subconsciously.

A 2023 study published in the Journal of Language and Linguistics found that documents with consistent grammar usage were rated as 27% more trustworthy by readers than those with grammatical inconsistencies, even when the content itself was identical.

Is 'tomatos' ever considered correct English?

No, 'tomatos' is not considered correct in standard English. While it occasionally appears in informal writing or speech, all major dictionaries and style guides recognize only 'tomatoes' as the proper plural form.

Why do we add -es to tomato instead of just -s?

We add -es to 'tomato' because it follows a specific English pluralization rule: words ending in -o preceded by a consonant typically form their plural by adding -es. This pattern applies to many food words of Spanish or Italian origin like 'potato' and 'hero.'

How do you pronounce the plural of tomato?

The plural 'tomatoes' is pronounced tuh-MAY-toes (with three syllables). The 'a' in the second syllable sounds like the 'a' in 'day,' and the final 'es' creates a distinct third syllable.

Are there any exceptions to the tomato plural rule?

Yes, some words ending in -o can take either -s or -es (like 'mosquito/mosquitos or mosquitoes'). However, 'tomato' isn't one of these exceptions—all authoritative sources agree that 'tomatoes' is the only correct plural form.

Does the plural form change in British versus American English?

No, 'tomatoes' is the standard plural form in both British and American English. Unlike some words that have different spellings across English varieties (like 'colour/color'), the plural of tomato remains consistent worldwide.
