Valleys is the correct spelling, while vallies is a common misspelling. The word valleys is the plural form of valley, which describes a low area of land between hills or mountains, often containing a river or stream.
If you are writing about several scenic landscapes, geographical features, or low areas between hills, you should use valleys, not vallies.
People often search for vallies or valleys because English plural spelling rules can be confusing. Some nouns ending in y change the y to ies when they become plural, such as baby becoming babies.
However, words ending in a vowel followed by y usually form their plurals by adding s. Since valley ends in ey, its plural is valleys.
Understanding this rule makes the correct spelling easier to remember. If you are writing a school assignment, describing a mountain landscape, preparing a travel article, or creating educational content, choosing valleys will keep your writing accurate.
This guide explains the meanings, spelling rules, word history, common mistakes, and everyday examples to help you confidently distinguish vallies from valleys.

Vallies and Valleys: Definition and Meaning
Understanding the meaning of valley helps explain why valleys is the correct plural form.
What Does Valley Mean?
A valley is a low area of land between hills or mountains. Valleys may be formed by rivers, glaciers, tectonic activity, or other natural processes. Many contain fertile soil, forests, streams, villages, and agricultural land.
Valleys can vary greatly in size. Some are narrow and steep sided, while others are broad, flat, and surrounded by rolling hills. They are important geographical features because they often provide routes for transportation, places for settlement, and suitable land for farming.
Examples of valley in a sentence:
- The village lies in a peaceful valley.
- A river flows through the valley.
- We watched the sunrise from a hill overlooking the valley.
- The valley is surrounded by tall mountains.
In each sentence, valley refers to one low area of land.
What Does Valleys Mean?
Valleys is the plural form of valley. It refers to two or more low areas of land between hills or mountains.
The word is commonly used in geography, travel writing, environmental studies, literature, and everyday conversation.
Examples of valleys in a sentence:
- The region is famous for its green valleys.
- Several valleys separate the mountain ranges.
- The hikers crossed three valleys before reaching the campsite.
- Heavy rainfall filled the valleys with flowing streams.
Whenever you are referring to more than one valley, use valleys.
What Does Vallies Mean?
Vallies is not the standard plural spelling of valley. Although people sometimes write it by mistake, it does not follow the accepted English spelling rule for this word.
The confusion often occurs because many nouns ending in a consonant followed by y change the final y to ies in the plural.
For example:
- Baby becomes babies.
- City becomes cities.
- Story becomes stories.
- Valley becomes valleys.
The final example follows a different pattern because valley has a vowel immediately before the y.
The Origin and History of Valley and Valleys
The history of valley helps explain its spelling and its connection to geographical descriptions.
Where Does the Word Valley Come From?
The English word valley entered the language through Old French valee, related to val, meaning a valley or lowland. Its deeper history is connected to Latin vallis, meaning a valley.
Over time, valley became the standard English word for a low area between hills or mountains. It is now used in geographical descriptions, place names, scientific writing, and figurative expressions.
For example, the term Silicon Valley refers to a region associated with technology and innovation. In this name, valley also identifies a geographical region, although the expression has developed a wider cultural and economic meaning.
How Did Valleys Become the Plural?
English forms the plural of most countable nouns by adding s or es. The word valley follows the simple pattern of adding s.
The spelling changes from valley to valleys, without removing the final y.
This is different from words such as city, where the consonant before the final y causes the plural to change to cities.
The difference depends on the letter immediately before the final y:
- Valley ends in vowel + y, so it becomes valleys.
- City ends in consonant + y, so it becomes cities.
- Toy ends in vowel + y, so it becomes toys.
- Baby ends in consonant + y, so it becomes babies.
These patterns are consistent with standard English plural spelling rules.
Why Is Valleys Correct and Vallies Incorrect?
The main reason is the English plural rule for nouns ending in y.
The Vowel + Y Rule
When a noun ends in a vowel followed by y, add s to form the plural.
Examples:
| Singular | Plural |
| Valley | Valleys |
| Boy | Boys |
| Toy | Toys |
| Key | Keys |
| Day | Days |
| Monkey | Monkeys |
Since the word valley ends in ey, the final y remains unchanged when the noun becomes plural.
The Consonant + Y Rule
When a noun ends in a consonant followed by y, the usual plural rule is to change the y to ies.
Examples:
| Singular | Plural |
| City | Cities |
| Baby | Babies |
| Story | Stories |
| Country | Countries |
| Party | Parties |
| Puppy | Puppies |
This rule is the likely reason people mistakenly write vallies. They apply the consonant + y pattern to a word that actually ends in a vowel + y.
An Easy Trick to Remember the Correct Spelling
Look at the letter immediately before the final y.
If it is a vowel, usually add s. If it is a consonant, usually change y to ies.
For valley, the letter before y is e, a vowel. Therefore, the correct plural is valleys.
Remember this simple example: one valley, two valleys.
British English vs. American English: Vallies or Valleys
There is no British English versus American English spelling difference for this word. Both varieties use valley in the singular and valleys in the plural.
| Context | British English | American English |
| Singular noun | Valley | Valley |
| Plural noun | Valleys | Valleys |
| Incorrect plural | Vallies | Vallies |
| Geographic description | Green valleys | Green valleys |
| Example | The valleys are beautiful. | The valleys are beautiful. |
Writers in the United Kingdom, United States, Canada, Australia, and other English speaking regions should use valleys when referring to more than one valley.
The spelling does not change according to regional preferences. The same rule applies in formal writing, academic assignments, travel guides, and everyday communication.
