Roses taken as courtesies by this lovely little one (5)
I believe the answer is:
cutie
'roses taken as courtesies by this lovely little one' is the definition.
'cutie' can be an answer for 'lovely' (I've seen this before). I am not sure about the remainder of the definition.
'by this lovely little one' is the wordplay.
'by' says to put letters next to each other.
'this lovely' becomes 'cute' (both can mean attractive or adorable).
'little' means to remove the last letter (the word is not quite complete).
'one' becomes 'ie' (I am not sure about this - if you are sure you should believe this answer much more).
'cute' with its last letter taken off is 'cut'.
'cut' put next to 'ie' is 'CUTIE'.
Can you help me to learn more?
(Other definitions for cutie that I've seen before include "Endearing person" , "Smart female" , "lovely" , "an attractive thing" , "something pleasing" .)
