We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Incorrect lemma from lemmatizer
**Right:**
`[w.lemma_ for w in nlp('funnier')]` -> `['funny']` 

**Wrong:**
`[w.lemma_ for w in nlp('faster')]` ->`['faster']`

I think for word _faster_ lemma should be _fast_
