Herb found in bog by New England lake (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
fennel
'herb' is the definition.
(I know that fennel is a type of herb)
'bog by new england lake' is the wordplay.
'bog' becomes 'fen' (I've seen this in another clue).
'by' means one lot of letters go next to another.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'england' becomes 'e'.
'lake' becomes 'L' (geographical abbreviation).
'fen'+'n'+'e'+'l'='FENNEL'
'found in' is the link.
(Other definitions for fennel that I've seen before include "Strong-scented plant whose seeds and leaves are used in cookery" , "...and an aromatic flavourful herb" , "Garden herb" , "Vegetable resembling celery" , "Aromatic yellow plant of the parsley family" .)
