I believe the answer is:

styles

I'm a little stuck... Click here to teach me more about this clue!

'names' is the definition.
(styling is a kind of naming)

I cannot understand how the remainder of the clue works.

(Other definitions for styles that I've seen before include "where there was a mysterious affair involving Poirot" , "Fashions or distinctive modes" , "Approaches" , "Ways of writing, painting etc" , "Modes or designs" .)
