cohesion

Grammatical or lexical relationships that bind different parts of a text together and give it unity. Cohesion is achieved through various devices such as connectives, ellipses and word associations. These associations include synonyms, antonyms (for example, study/laze about, ugly/beautiful), repetition (for example, work, work, work – that’s all we do!) and collocation (for example, friend and pal in, My friend did me a big favour last week. She’s been a real pal.)
