Ellipsis
Ellipsis is another cohesive device. It happens when, after a more specific mention, words are omitted when the phrase needs to be repeated.
A simple conversational example:
- (A) Where are you going?
- (B) To town.
The full form of B's reply would be: "I am going to town".
A simple written example: The younger child was very outgoing, the older much more reserved.
The omitted words from the second clause are "child" and "was".
