Makes secure from wind (also building at back of garden) (5,4)
I believe the answer is:
nails down
'makes secure' is the definition.
I can't judge whether this defines the answer.
'wind also building at back of garden' is the wordplay.
'building' indicates an anagram.
'at' means one lot of letters go next to another.
'back of' suggests the final letters.
The last letter of 'garden' is 'n'.
'wind'+'also'='windalso'
'windalso' is an anagram of 'nailsdow'.
'nailsdow'+'n'='NAILS DOWN'
'from' is the link.
Can you help me to learn more?
(Another definition for nails down that I've seen is " Clearly defines".)
