Usage

The adjective form 主体的(しゅたいてき) (proactive, self-directed) is very commonly used in education and business contexts, meaning to act on one's own initiative rather than passively following instructions.

The pattern ~主体(しゅたい) is used as a suffix meaning "-led" or "-centered" (e.g., 学生(がくせい)主体(しゅたい) = student-led).
