A short trip made to do a specific task, often for someone else.

Errand comes from Old English 'ærende' (meaning message or command). The word refers to a task or mission, often involving a message or request to be delivered.
Think of an 'errand' as a 'message' or 'command' that you need to carry out — that's why it refers to a task you do.
