Dill or chervil, eg (4)
I believe the answer is:
herb
This clue is a double definition.
'dill' is the first definition.
(thesaurus)
'chervil eg' is the second definition.
(chervil is a kind of herb)
(Other definitions for herb that I've seen before include "Thyme, for example" , "Basil, for example, is one" , "Rosemary perhaps" , "Wayside plant with small red flowers" , "Plant used in medicine or for flavouring" .)
