How to Pronounce Loose and Lose
The two words have the same long vowel sound, but their final consonants differ.

|---|---|---|
| Loose | /luːs/ | s, as in goose |
| Lose | /luːz/ | z, as in choose |
The final /s/ in loose is unvoiced, while the /z/ in lose is voiced, meaning the vocal cords vibrate.
This pronunciation distinction is the same in standard American and British English.
The spelling can be misleading because lose has only one o, yet it shares the same vowel sound as loose.
A simple memory trick is to associate the extra o in loose with extra room or space. For lose, remember the related words lost and loss.
