Both express fear, but one is more formal and lasting, and the other is more colloquial and can describe an instant fright.
Side-by-side comparison
"Afraid" expresses fear or worry about something. It is more formal and can also mean regret: "I'm afraid I can't help" = I'm sorry, I cannot help.
She is afraid of flying.
Are you afraid of the dark?
He was afraid that he would fail the exam.
"Scared" expresses fright or fear in a more direct and informal way. It is the immediate, physical feeling of being frightened. It does not have the secondary meaning of regret.
The children were scared by the loud thunder.
I was scared when I heard the strange noise at night.
She is a scared little puppy. Do not yell at her.
Common mistake
- •You cannot use "afraid" before a noun: "an afraid child" is wrong.
- •If you need the adjective before the noun, use "scared" or "frightened": "a scared child".
Trick to remember it
- •AFRAID is predicative only: it always follows a verb (be/seem/feel). "She is afraid" ✓ — but "an afraid child" doesn't exist.
- •SCARED is the full adjective: "a scared child" ✓ (attributive) + "She is scared" ✓ (predicative).
- •Emergency rule: not sure? SCARED always works. AFRAID can't go before a noun.
Quick rule
- •"Afraid" = only after a verb (she is afraid).
- •"Scared" = before or after a noun, more colloquial.
Did you know?
"Frightened" is a formal synonym that, like "scared", can go before or after a noun. "Terrified" signals extreme fear. "Fearful" is very formal, almost literary. And "petrified" (literally "turned to stone") is used colloquially for paralyzing fear. In everyday conversation, "scared" is the most natural and versatile option of the bunch.
