relation

/rɪˈleɪʃɪn/

/rɪˈleɪʃən/

Other forms: relations

Relation is a word that can describe a connection — between relatives or any two entities. You might consider your cousin as your relation, and you might have strained relations with him over your grandmother's estate.

The way that one thing affects another is their relation like the relation between childhood poverty and poor nutrition, for example. You can also call your relative a relation, as when you describe your great-grandfather as your oldest living relation. The phrase no relation means that even though two people share the same last name, they are not related — or aren't relations.
