Explanation:

• For "middle" category:
• The word "intermediate" has the root "medi -" which can imply a sense of being in the middle. "Inter -" means between, so "intermediate" is something between two things (in the middle range).
• "Mediate" also has the "medi -" root. It means to act as an intermediary (in the middle) between two parties.
• "Medium" (in the sense of being an average or middle - level thing) has the "medi -" root related to the concept of middle.
• "Mediterranean" (the sea is named so as it is in the middle of lands in a certain sense, with "medi -" root).
