together (with); -wide
Attach to nouns to mean 'together with' or 'the whole ...', expressing that something involves the entire entity or group.
ぐるみ is a suffix that attaches to nouns to express that an action or state covers the whole of that noun, often implying joint effort or total involvement. It is similar to saying 'together with the entire X' or 'X-wide' in English. For example, 町ぐるみ (machi-gurumi) means 'whole town' or 'town-wide'. The noun it attaches to is the entire entity participating or affected, and the pattern is often used with movement or action verbs to show that everyone or everything is involved as a unit.
