معنا
A tool or means is what someone uses to carry out an action. It can be an object, a body part, a way of traveling, or a way of sending information. Languages express this with separate words, endings, or context; some have no special marker for it. Tool or means identifies what is used, while How the tool is marked looks at the words or endings that connect it to the action.

Ask what is used to carry out the action, rather than who does it or who benefits from it.
