What’s the Plural of Chief? Understanding the Correct Form

Chief, Chiefs — See the Pattern

Some words that end in -f change to -ves in the plural. But chief is not one of them. Look at these examples:

• one chief → two chiefs (just add -s)
• one wolf → two wolves (changes to -ves)
• one belief → two beliefs (just add -s)
• one knife → two knives (changes to -ves)

Did you see the pattern? Some -f words change to -ves, but others just add -s. The word chief is one that just adds -s.

Why It Is Chiefs and Not Chieves

Many learners think chief should change to “chieves” because words like wolf → wolves and leaf → leaves follow that pattern. But chief does not work that way.

Here is the simple rule:

• If a word ends in -ief, -oof, or -ff, it usually just adds -s.
• If a word ends in -lf, -fe, or -af, it often changes to -ves.

Look at the examples:

• chief → chiefs (ends in -ief, just add -s)
• roof → roofs (ends in -oof, just add -s)
• wolf → wolves (ends in -lf, changes to -ves)
• knife → knives (ends in -fe, changes to -ves)

Easy way to remember: Think of a chef in a kitchen. Would you ever say “cheves”? No — you say chefs. The word chief works the same way. Just add -s.

How to Use Chiefs in Everyday English

• The fire chiefs from three towns met yesterday. (more than one fire chief)
• Our company has two chiefs — a CEO and a CTO. (more than one leader)
• The tribal chiefs agreed on a plan. (more than one tribal leader)
• She is the chief of the department. (just one leader)
• Three police chiefs spoke at the event. (more than one police chief)

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

The Most Common Mistake With Chief

Even advanced learners write “chieves” sometimes — so if you have made this mistake, you are not alone. It happens because other -f words like wolf and leaf do change to -ves. Your brain sees the pattern and tries to use it everywhere.

How to remember: Words that end in -ief always just add -s. Think: chief → chiefs, belief → beliefs, brief → briefs, relief → reliefs. The -ief ending never changes to -ieves as a plural.

Other words that just add -s: roof → roofs, chef → chefs, cliff → cliffs, proof → proofs.

Keep Going — You Are Building Something

You just learned that chief becomes chiefs. That is one more plural you will never get wrong again.

But here is something interesting. You now know that chief keeps its -f and just adds -s. But what about the word belief? It also ends in -f. Does it become “beliefs” or “believes”? And why do those two words mean completely different things?
