You are doing great. Now let’s look at the mistakes many learners make with this word.

The Most Common Mistake With Salmon
Even native speakers’ children say “salmons” when they are learning to talk — so if you make this mistake, you are not alone. Your brain wants to add -s because that is the normal rule. But salmon is a special word.
Mistake 1: Adding -s for many
✗ I saw five salmons in the river.
✓ I saw five salmon in the river.
Mistake 2: Using the wrong verb
✗ The salmon is swimming upstream. (talking about many)
✓ The salmon are swimming upstream. (talking about many)
Mistake 3: Using “salmons” as a possessive
✗ The salmons’ eggs are in the gravel.
✓ The salmon’s eggs are in the gravel.
How to remember: Think of the word salmon like the word water. You do not say “two waters.” You just say “water.” Salmon works the same way — the word itself never changes.
Other words like this: deer → deer, sheep → sheep, fish → fish, trout → trout.

Keep Going — You Are Building Something
You just learned that salmon never changes — one salmon, many salmon, always the same. That is one more word you will never get wrong again.
But here is something interesting. The word deer works the same way — one deer, two deer. But what about the word “deers”? Is it ever correct? And why do some animals keep the same plural while others add -s?
