Couple
In short
Two people who are joined together in a romantic relationship or marriage.
In plain words
A couple consists of two individuals who share a close bond. They often live together or make life decisions as a pair.
A simple example
Tom and Sarah have been a couple for five years. They recently decided to buy a house together.
Why it matters
Couples form the basic building blocks of many families and social structures. They provide emotional support and companionship to one another.
Easy to mix up
Do not confuse a romantic couple with a pair of objects or a duo of performers.
