Conversion
A word formation process where a word changes grammatical class without morphological change, such as 'google' (noun to verb) or 'impact' (noun to verb in 'to impact outcomes').
Real World
When Google launched in 1998 it was a noun (a search engine), but by 2006 'google' had been converted into a verb so widely that Merriam-Webster added 'to google' as a dictionary entry.
Exam Focus
State both the original and new word class explicitly — examiners reward precise grammatical labelling.
