Have you ever typed “vallies or valleys” and stopped to wonder which spelling is right? You are not alone. English plural rules can be confusing, especially with words that end in -y.
The correct spelling is valleys. It is the plural form of valley, meaning low areas of land between hills or mountains. Vallies is not the standard modern spelling, although it can be found as an obsolete historical plural in older texts.
People often search for “vallies or valleys” because they remember the rule that changes words such as city to cities and baby to babies. That can make valley → vallies seem logical. However, the spelling rule depends on the letter before y.
This guide explains the difference, the history of the word, British and American usage, common mistakes, everyday examples, and how to remember the correct spelling. By the end, you will know exactly when to use valleys and why vallies should normally be avoided.
Vallies or Valleys – Quick Answer
Valleys is the correct spelling in modern standard English.
- ✅ Valleys = correct plural of valley
- ❌ Vallies = incorrect in modern standard usage
A valley is a low area of land between hills or mountains. The plural is valleys.
Examples:
- The hikers walked through several valleys.
- The mountains contain deep, green valleys.
- Heavy rain caused flooding in nearby valleys.
The reason is simple: valley ends in -ey. Because the y follows a vowel, you normally add -s to form the plural.
Compare:
| Singular | Plural |
|---|---|
| valley | valleys |
| key | keys |
| monkey | monkeys |
| journey | journeys |
By contrast, words ending in a consonant + y usually change y to i and add -es:
| Singular | Plural |
|---|---|
| city | cities |
| baby | babies |
| country | countries |
| story | stories |
So, valley → valleys, not vallies.
The Origin of Vallies or Valleys
The word valley has a long history. Merriam-Webster traces it through Middle English valeye to Anglo-French valee, ultimately connected with Latin vallis, meaning “valley.” Its first known English use dates to the 14th century.
The spelling vallies has also appeared in historical English. It is recorded as an obsolete plural of valley in older works, including writings from the 18th and 19th centuries.
However, modern English settled on valleys as the standard plural.
Why Do People Write “Vallies”?
The main reason is confusion about English plural rules.
Consider:
- city → cities
- party → parties
- family → families
These words end in a consonant before y, so the y changes to i.
But valley is different:
- valley → the letter before y is e, a vowel
- Therefore, add s
- valley → valleys
The same pattern appears in words such as key → keys and monkey → monkeys.
British English vs American English Spelling
There is no British-American spelling difference for this word.
Both British English and American English use valleys as the standard plural.

|---|---|---|

| “Vallies” | Not standard | Not standard |
| Formal usage | valleys | valleys |

This is different from words such as colour/color or centre/center. With valleys, writers in both varieties use the same spelling.
A Simple Rule

- toy → toys

Examples:
- city → cities
