# Code Smell 171 - Plural Classes

> TL;DR: Classes represent concepts. And concepts are singular.

# Problems

- Naming

- Code Standards

# Solutions

1. Rename classes to singular

# Context

Naming things is hard.

We need to agree on certain rules.

# Sample Code

## Wrong

[Gist Url]: # (https://gist.github.com/mcsee/5d0c869a94d623684baefce9897563e2)
```scala
class Users
```

## Right

[Gist Url]: # (https://gist.github.com/mcsee/34c2fa54fa1629971b55d084541e9ce2)
```scala
class User
```

# Detection

[X] Automatic 

This is a syntactic rule.

# Tags

- Naming

# Conclusion

Name concepts in the singular.

Classes are concepts.
