This document discusses different types of synonymy: 1. Near synonymy, where expressions are similar but not identical in meaning. Examples given are mist-fog and stream-brook. 2. Partial synonymy, where expressions match in identity of meaning but fail to meet conditions of absolute synonymy. The example given is car-vehicle. 3. Absolute (perfect, complete) synonymy, where words match in all shades of meaning and stylistic characteristics. Examples given are airman-pilot and car-automobile. Absolute synonyms are rare for lexemes but more common for composite expressions.
