It's easy to find in the herb garden (6)
I believe the answer is:
simple
This might be a double definition.
'it's easy' is the first definition.
(similar in meaning)
'find in the herb garden' is the second definition.
'simple' can be an answer for 'garden' (thesaurus). I'm unsure of the 'find in the herb' bit.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for simple that I've seen before include "half-witted" , "Straightforward, not elaborate" , "Easy to understand" , "Impels (anag.)" , "Plain and uncomplicated" .)
