Common Mistakes

Mistake 1: Using “proscribe” when you mean “prescribe”

Incorrect:

The doctor proscribed antibiotics.

This means the doctor forbade antibiotics.

Correct:

The doctor prescribed antibiotics.

Mistake 2: Assuming “proscribe” means “recommend”

Because the two words look similar, writers sometimes treat them as synonyms.

They are not synonyms.

Prescribe involves recommending, ordering, or specifying.
Proscribe involves prohibiting.

Mistake 3: Confusing “proscribe” with “prescription”

A prescription is an instruction or authorization, usually from a medical professional, for medicine or treatment.

Proscription means an official prohibition or ban.

Mistake 4: Using “prescribe” for every type of rule

Although prescribe can mean “specify,” it often sounds formal when used for general rules. Depending on the context, require, specify, or mandate may sound more natural.

Memory Trick: Prescribe vs Proscribe

Try this simple trick:

PRESCRIBE = PROVIDE

Both begin with P and can be connected with the idea of providing instructions or treatment.

Prescribe = provide what should be used or done.

PROSCRIBE = PROHIBIT

Both proscribe and prohibit begin with PRO.

Proscribe = prohibit something.

So remember:

Prescribe = do/use this.
Proscribe = don’t do/use this.

This simple contrast is usually enough to keep the two words apart.

American vs British English
