A doing word. For example, in the phrase “the solicitor butchered the English language,” “butchered” is the verb.

A good way to butcher the language is to covert your verbs to nouns. You can do this easily: take an interesting verb (like butcher), castrate it by adding a duller verb in front of it (like “to subject to”) and then humiliate it with an ugly suffix. For example a y, or an ification.

The solicitor butchered the English language
The solicitor subjected the English language to butchery.

Extra points are available if you can convert an active noun into the passive at the same time. For this, your best friends are obliged to be applicable.
