na-adjective
self-directed; proactive; independent; responsible
Describes acting, deciding, or learning on one's own initiative as the responsible agent, rather than merely following others or being passive. Often used as 主体的に or 主体的な.
学生には主体的に学ぶ姿勢が求められる。
Students are expected to have an attitude of learning proactively.
She gathered information herself and made an independent decision.
na-adjective
subjective; relating to the subject
A less common academic or philosophical use close to 主観的, focusing on the perceiving or acting subject. For everyday 'subjective opinion,' 主観的 is usually the clearer word.

哲学の文脈では、「主体的」は主観的に近い意味で使われることがある。
In philosophical contexts, 主体的 is sometimes used in a sense close to 'subjective.'
Also means voluntary or autonomous, but it emphasizes doing something by one's own choice; 主体的 adds a stronger sense of active engagement and responsibility.
Means active rather than passive; 主体的 overlaps when describing initiative, but more strongly suggests independent judgment and ownership of the action.
Sino-Japanese compound from 主体, 'subject, agent, main body,' plus the adjectival suffix 的, '-ic; -al.' The spelling transparently matches the modern meaning; no more specific historical derivation is asserted here.
