Basil or rosemary (4)
I believe the answer is:
herb
I believe this clue is a double definition.
'basil' is the first definition.
(basil is an example)
'rosemary' is the second definition.
(thesaurus)
(Other definitions for herb that I've seen before include "Basil, for example, is one" , "ingredient for recipe?" , "Marjoram, say" , "Wayside plant with small red flowers" , "plant with useful properties" .)
