On a new Terminal:

```
> set | grep LC_
LC_COLLATE=en.UTF-8
LC_CTYPE=en.UTF-8
LC_MESSAGES=en.UTF-8
LC_MONETARY=en.UTF-8
LC_NUMERIC=en.UTF-8
LC_TIME=en.UTF-8
```

default/fallback:

```
> unset LANGUAGE && unset LC_ALL && unset LC_TIME
> git bla
git: 'bla' is not a git command. See 'git --help'.

The most similar command is
        blame
```

LC_TIME is the only LC_* envar besides LC_ALL that changes the language in output:

```
> LC_TIME=es git bla
git: 'bla' no es un comando de git. Mira 'git --help'.

El comando más similar es
        blame
```

LC_ALL overrides it:

```
> LC_ALL=en LC_TIME=es git bla
git: 'bla' is not a git command. See 'git --help'.

The most similar command is
        blame
```

And LANGUAGE overpowers them both:

```
> LANGUAGE=es LC_ALL=en LC_TIME=es git bla
git: 'bla' no es un comando de git. Mira 'git --help'.

El comando más similar es
        blame
```
