Saw for example in front of garden (6)
I believe the answer is:
saying
'saw' is the definition.
(a saw can mean a proverb or maxim)
'for example in front of garden' is the wordplay.
'for example' becomes 'say' ('say' can be used to introduce an example).
'front of' says to take the initial letters.
The initial letter of 'garden' is 'g'.
'say'+'in'+'g'='SAYING'
(Other definitions for saying that I've seen before include "Gnome" , "Apophthegm" , "Motto" , "Speaking; adage" , "Well-known phrase or proverb - just speaking" .)
