Quick answer
In everyday cooking, prawn and shrimp both describe small, edible shellfish, and many recipes use the words interchangeably. A useful memory hook: shrimp is also used informally for a small or unimportant person, a sense prawn does not share.
The core difference
Both are edible shellfish terms, but shrimp carries an extra informal meaning that prawn does not.
- prawn — a shellfish, often eaten as seafood: We ordered a plate of garlic prawns to share.
- shrimp — a small, edible crustacean, or informally a small or unimportant person: We grilled shrimp skewers for the barbecue.
How to tell them apart
Since both words point to the same kind of seafood, the easiest way to keep them apart is the insult sense: only shrimp can describe a person as small or unimportant, as in being teased for being a shrimp. Prawn has no such secondary meaning, so it stays purely a seafood word.
The mix-up rarely causes confusion in practice, since a menu or recipe using either word is still describing the same kind of dish.
