"Thyme" or "basil" (4)
I believe the answer is:
herb
I believe this is a double definition.
'thyme' is the first definition.
(thesaurus)
'basil' is the second definition.
(basil is an example)
(Other definitions for herb that I've seen before include "'Sage or rosemary, say (4)'" , "like Basil" , "Maybe sage" , "Parsley, for instance" , "Eg, sage" .)
