A friend of mine sent a broadcast message and said her wedding is a couple of weeks away. I cringed, knowing that the wedding was about eleven weeks away. Now, that is not a couple of weeks.
According to Oxford English Dictionary, a couple means:
a. two people or things of the same sort considered together: a couple of girls were playing marbles
b. [treated as singular or plural] two people who are married or otherwise closely associated romantically or sexually: in three weeks the couple fell in love and became engaged a honeymoon couple
c. (Informal) an indefinite small number
1. a: two persons married, engaged, or otherwise romantically paired
b: two persons paired together
2. : pair, brace
3. something that joins or links two things together: as
a: two equal and opposite forces that act along parallel lines
b: a pair of substances that in contact with an electrolyte participate in a transfer of electrons which causes an electric current to flow
4. : an indefinite small number : few <a couple of days ago>
‘A couple’ naturally indicates the number two. However, it can also mean an indefinite small amount of time. This means that if you say ‘a couple of weeks’ it means two to three weeks, four weeks on the maximum.
