## C/C++ Compound Words

It is very common for C/C++ code to contain word compound like `errorcode` and `hashcode`.
The `cpp-compound-words` dictionary is designed to help avoid false positives. But, this can
mean that valid errors are hidden due to the way compounds are combined.

The following configuration can be used to disable the compound dictionary:

```yaml
languageSettings:
  languageId: 'c,cpp' # '*' can be used to disable it for all file types.
  dictionaries:
    - '!cpp-compound-words'
```
