Crawl from small wood and lake (6)
I believe the answer is:
grovel
'crawl' is the definition.
('grovel' can be a synonym of 'crawl')
'small wood and lake' is the wordplay.
'small wood' becomes 'grove' (I've seen this before).
'and' means one lot of letters go next to another.
'lake' becomes 'l'.
'grove'+'l'='GROVEL'
'from' acts as a link.
(Other definitions for grovel that I've seen before include "Display abject humility" , "Behave obsequiously, humble oneself" , "Crawl, fawn" , "Cringe in abject manner" , "Prostrate oneself" .)
