Can you tell me the differences between Cohesion and Coherence?
When did we use Cohesion or Coherence?
I'm really confused about how to use and explain them.
(When speaking of a relationship of any kind - business, sexual ... - we tend to use the related word 'cohesiveness'.)
Coherence is holding together, structurally - as in 'the coherence of his argument'.
For further details, 'let your fingers do the walking' (many online dictionaries).
