How we represent qualifiers in data model?

From https://en.wiktionary.org/wiki/qualifier#English:

> (grammar) A word or phrase, such as an adjective or adverb, that describes or characterizes another word or phrase, such as a noun or verb; a modifier; that adds or subtracts attributes to another.

Can we consider it as another part of speech (although in fact it's not)? Or maybe we need a separate field for that?

Feel free to move this issue to glossarist/concept-model if you find it more appropriate.

Start by reviewing the existing data model and how the listed Electropedia examples are represented. Compare treating qualifiers as parts of speech with representing them in a separate field; done requires a decided model for qualifiers and agreement on the examples.
