Motivation: I'm doing a text-mining project and I'd like to map all forms of an adjective to their "base-form".
Example:
bigger -> big
biggest -> big
stronger -> strong
strongest -> strong
The words on the left are the comparitive or superlative forms of the word on the right.
Question: What is the word on the right called?
Related: Antonym of "superlative", but in this case I'm not looking for the opposite, simply the name of the form without the comparison.
