- "The term coordination refers to syntactic constructions in which two or more units of the same type are combined into a larger unit and still have the same semantic relations with other surrounding elements." (Haspelmath 2007:1)
The corresponding relational adjective is coordinative (though coordinate is also used).
- coordination of NPs: the moon and the sun
- coordination of clauses: The children are playing and the grown-ups are talking.
- coordination of adverbs: Does he play well or beautifully?
- conjunction (= conjunctive coordination) ('X and Y')
- disjunction (= disjunctive coordination) ('X or Y')
- adversative coordination ('X but Y')
The term coordination seems to have been coined only in the 19th century. In the earlier literature, the term copulative was often used for coordination.
