Hurried to secure new outlay (5)
I believe the answer is:
spend
'outlay' is the definition.
(I've seen this before)
'hurried to secure new' is the wordplay.
'hurried' becomes 'sped' ('speed' can be a synonym of 'hurry').
'to secure' means one lot of letters goes inside another.
'new' becomes 'n'.
'sped' placed around 'n' is 'SPEND'.
(Other definitions for spend that I've seen before include "Blue" , "Use up (one's resources)" , "While away" , "Part with money" , "Pass time or pay out" .)
