Ask me about various brands (5)
I believe the answer is:
makes
'various brands' is the definition.
'makes' can be an answer for 'brands' ('make' can be a synonym of 'brand'). I'm not sure about the 'various' bit.
'ask me about' is the wordplay.
'about' is an anagram indicator.
'ask'+'me'='askme'
'askme' anagrammed gives 'MAKES'.
Can you help me to learn more?
(Other definitions for makes that I've seen before include "Fabricates or comples" , "Builds" , "Creates" , "Forms" , "Constructs" .)
