Description

The word "using" is lemmatized incorrectly:

import pattern.en

print("using", pattern.en.lemma("using"))
print("use", pattern.en.lemma("use"))

The result is:

using used
use use

For comparison, both amusing and amuse return the same lemma amuse.

This issue, in turn, breaks conjugation, so that conjugate("using", "1sg") returns used.

Research direction

Start by reproducing the reported results with pattern.en.lemma("using") and conjugate("using", "1sg"), then compare them with the expected lemma "use" and the behavior of "amusing" and "amuse". Done means "using" is lemmatized as "use" and conjugation no longer returns "used".
