Desire to get a breath of fresh air (10)
I believe the answer is:
aspiration
'desire' is the definition.
(I know that aspiration is a type of desire)
'a breath of fresh air' is the wordplay.
I cannot quite see how this works, but
'a' is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
an anagram of 'air' is 'ira' which is present in the answer.
This explanation may well be incorrect...
'to get' acts as a link.
Can you help me to learn more?
(Other definitions for aspiration that I've seen before include "Hope" , "Craving" , "Drawing breath" , "Eager desire" , "With which to announce Hammers' first" .)
