1.
errand; shopping trip (on someone's behalf)
Going out to buy something or deliver something on behalf of someone else. Commonly used when a parent sends a child to the store, or when someone runs errands for the household.
The お prefix is standard and nearly always used; the bare form 使い sounds blunt and is rarely heard.
Common patterns
Cultural note
'初めてのお使い' (My First Errand) is a popular Japanese TV show where small children are sent on errands alone for the first time, watched by hidden cameras. The concept reflects the cultural practice of gradually giving children independence through errands.
Usage
Most commonly associated with children being sent to buy something at a nearby store. For adult errands in a business context, 用事 (business, things to do) is more natural.
