Maybe it’s because lose rhymes with choose. Maybe it’s because too many writers snooze or drink booze or get tattoos or play kazoos.
Whatever the reason, sometimes when we mean to write lose – to misplace, not win, elude – we accidentally write loose – unfastened, not precise, freed.
We know better. It happens when we’re rushed or not paying attention. We hope it will be caught – by us or a friend or an editor – before it is published and a large number of readers see it. After all, we don’t want too many people thinking we’re dumb.
