Onomatopoeic adverb meaning 'tightly', 'snugly', or 'closely'. Emphasizes close contact or perfect fit.

Do not directly translate 'closely' as a single Japanese word in all contexts. The appropriate expression depends heavily on the intended meaning. Using 近くに for 'listen closely' would sound unnatural.
Both mean 'closely' in abstract connections. 密接に is more general (relationships, links), while 緊密に is often used for cooperation or coordination. 密接に is slightly more common.
