Themes
communication

|exact correspondence
|direct correspondence
|lack of correspondence
|show a correspondence
Synonyms
similarity (General word; does not always suggest as precise a match as "correspondence" can.)

Antonyms
mismatch (Emphasizes that two things do not fit or match each other.)

|set correspondence
|establish a correspondence
Synonyms
