literature is a facilitating subject, although thats not such an emphasised concept today. Language is good for developing skills where you're encouraged to brainstorm and persuade (could link to law) whilst literature is good for analysing and thinking of creative interpretations (could link to both law and psych). Personally as someone who is planning to study clinical psych in the future, i took literature. best decision ever, its my therapy subject haha. good luck with your decision!
