Common Errors

Memory Trick

Waist contains the word "waist" — think of "waist" as having just the letters needed and nothing more, like a trimmed midsection. The word waist itself refers to trimness and the narrow middle.

Waste contains the letters for "wasted" — the root word connects to discarding, losing, and inefficiency. If you can think of the adjective "wasteful," that anchors the correct spelling.
