Common Mistakes

MISTAKE: Thinking 'quad' means any small number, like two or three. | CORRECTION: Remember 'quad' specifically means four, never any other number.

MISTAKE: Confusing 'quad' with 'quart'. | CORRECTION: 'Quad' refers to a group of four. 'Quart' is a unit of measurement, usually for liquids, and often related to one-fourth of a larger unit.

MISTAKE: Using 'quad' for a group of five or more. | CORRECTION: 'Quad' is only for a group of exactly four. For five, you might say 'quintet', but 'quad' is strictly four.
