Table of Contents

3. DEFINITION SECTION

3.1. What is a Plural Noun?

A plural noun refers to more than one person, place, thing, or idea. In English, we typically create plurals by adding -s or -es to the singular form.

Plural nouns help us distinguish between a single item and multiple items, which is essential for clear communication. Consider these examples:

  • cat → cats
  • dog → dogs
  • book → books

Most English nouns follow these simple rules, but some have irregular forms or special patterns, especially nouns ending with certain letters.

3.2. What is the Plural Form of ‘Tomato’?

The correct plural of tomato is tomatoes.

Tomato is a countable, concrete, common noun. This means:

  • We can count individual tomatoes (one tomato, two tomatoes).
  • It refers to a tangible object.
  • It is a general noun, not a specific name.

The singular refers to one fruit (botanically a berry), and the plural, tomatoes, refers to two or more.

3.3. Why Is ‘Tomato’ Pluralized Differently?

Unlike most nouns that take a simple -s, tomato requires -es in the plural: tomatoes.

This is because tomato ends with the letter -o preceded by a consonant (the letter t). Many such nouns form the plural by adding -es instead of just -s.

3.4. Usage Contexts

The plural tomatoes appears widely in:

  • Everyday conversation: “I bought some tomatoes.”
  • Academic/scientific writing: “Tomatoes are rich in vitamins.”
  • Cooking and recipes: “Chop the tomatoes finely.”
  • Formal and informal settings: The plural form remains the same regardless of context.

4. STRUCTURAL BREAKDOWN

4.1. General Rule for Pluralizing Nouns

The most common way to form a plural noun in English is to add -s to the singular:

Singular Plural Notes
car cars Simply add -s
book books Simply add -s
pen pens Simply add -s
tree trees Simply add -s
student students Simply add -s

4.2. Nouns Ending in -o: The Special Case

For nouns ending with -o, pluralization rules vary. Sometimes we add only -s, but often we add -es.

Why add -es? Adding -es instead of just -s makes pronunciation easier, especially when the word ends with a consonant + o. Historically, some words adopted this pattern under the influence of Italian and Spanish.

4.3. Rule for ‘Tomato’

Because tomato ends with consonant + o, its plural is formed by adding -es:

  1. Identify last letter: -o
  2. Check the preceding letter: consonant (t)
  3. Apply rule: Add -es → tomatoes

4.4. Other -o Ending Nouns: Patterns and Comparisons

Let’s compare similar nouns:

Singular Plural Consonant + o? Pluralization method
tomato tomatoes Yes add -es
potato potatoes Yes add -es
hero heroes Yes add -es
echo echoes Yes add -es
torpedo torpedoes Yes add -es
cargo cargoes / cargos Yes both accepted
piano pianos Yes add -s
photo photos Yes add -s
radio radios Yes add -s
zero zeros / zeroes Yes both accepted
video videos Yes add -s
memo memos Yes add -s
avocado avocados Yes add -s
banjo banjos Yes add -s
buffalo buffaloes / buffalos Yes both accepted

Note that some words accept both forms (like cargoes/cargos), but tomato only correctly pluralizes as tomatoes.

4.5. Historical and Linguistic Background

Tomato comes from the Spanish word tomate, which itself originates from the Nahuatl (Aztec language) word tomatl.

Since tomato entered English via Spanish in the 16th century, it followed the pluralization rules common for other nouns ending with consonant + o, adopting -es to aid pronunciation and conform to patterns like potato → potatoes.

5. TYPES OR CATEGORIES

5.1. Regular Plural of Tomato: Tomatoes

The plural tomatoes is the standard, correct form in all contexts where you refer to more than one tomato.

5.2. Irregular or Nonstandard Variants (Misuses)

  • Tomatos: A common misspelling or incorrect plural form.
  • Colloquial/dialectal forms: Rarely, some dialects may simplify plurals, but tomatoes remains standard.

5.3. Plurals in Compound Words

When tomato appears in compound nouns, pluralization depends on what is counted:

  • Cherry tomatoes (multiple small tomatoes)
  • Tomato plants (multiple plants producing tomatoes)
  • Tomato sauce (uncountable, no plural)

5.4. Scientific or Specialist Usage

In botany, the Latin name is Solanum lycopersicum.

Naming follows Latin binomial conventions, so pluralization focuses on species or specimens, often not pluralized in the same way as common nouns.

5.5. Countable vs. Mass Noun Use

  • Countable: “Three tomatoes” (individual fruits)
  • Uncountable: “Add some tomato to the sauce” (ingredient, puree, mass noun)

As an uncountable noun, tomato does not take a plural form.
