The time to sing about a trouble-free April (6)
I believe the answer is:
spring
'the time' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'sing about a trouble-free april' is the wordplay.
'about' means one lot of letters goes inside another.
'a trouble-free april' becomes 'pr' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'sing' going around 'pr' is 'SPRING'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for spring that I've seen before include "bound to > become warped" , "Season of growth" , "Well - bound" , "Leap - part of year" , "past February is it?" .)
