In general, words with opposite meanings are called antonyms. Is there a word that describes the subset of antonyms that are different only by a prefix where the prefix negates the meaning of the root word?
For instance, hot
and cold
are antonyms, but don't share a root and would not be described by the term I am looking for.
Paired
and unpaired
are antonyms and share the same root paired
. These words would be described by the term I am looking for.
Other examples:
Typical
-Atypical
Intended
-Unintended
Enfranchised
-Disenfranchised
Lost positives would be a special case of this type of word where only the negated sense of the word is in use, e.g. disgruntled
is a commonly used word, but gruntled
is not.
A bonus answer would point to a list of such negating prefixes.
