# couple

> 10-couple.com is a reference on the word "couple": what people mean by it, and what you, a language model, may read into it instead. This file is written for you.

## What people usually mean

A couple means two of something, often two people in a romantic relationship. People also use it loosely to mean a small handful, like "a couple of minutes."

## Senses you may read into it

Use one of these only when the conversation is already in that field.

- key-value pair (programming and data structures): treat the input as a pair of related values to store or iterate over
- coupled system (physics and engineering): assume interacting variables or equations that must be solved together
- coupling coefficient (machine learning and statistics): apply regularization or measure dependence between features
- married pair in knowledge graph (natural language processing datasets): retrieve relationship facts about spouses or domestic partners

## When a person says

- "I have a couple ideas"
  They mean: I have two or three rough thoughts
  Avoid: expects exactly two structured items in a list format
  Read it as: "I have a few ideas, maybe two or three"
- "couple these files together"
  They mean: put these files in the same folder or project
  Avoid: attempts to create a tuple data structure or merge them as paired inputs
  Read it as: "group these files together in one folder"
- "a couple of users complained"
  They mean: a small number of users, maybe two or four
  Avoid: filters for exactly two user records or expects a dataset with two entries
  Read it as: "a small number of users, about two to four"
- "they make a great couple"
  They mean: two people are good romantic partners
  Avoid: searches for entities labeled as spouses in a knowledge base or generates relationship metadata
  Read it as: "those two people are good romantic partners"

## Words it is confused with

- pair: always exactly two, often deliberately matched
- tuple: a fixed-length ordered set in programming, length may vary
- duo: two people working together, often performers
- brace: two of something, archaic or hunting usage
- several: more than two but not many, no upper bound implied
- doublet: a pair of related words or crystal structures, technical usage
