Inviting axes to be applied to last of trees here (4)
I believe the answer is:
sexy
'inviting' is the definition.
(thesaurus)
'axes to be applied to last of trees here' is the wordplay.
'axes' becomes 'xy' (x axis and y axis).
'to be applied to' says to put letters next to each other.
'last of' says to take the final letters.
The last letters of 'trees here' are 'se'.
'xy' put after 'se' is 'SEXY'.
(Other definitions for sexy that I've seen before include "Attractive (sl.)" , "arousing passion" , "Seductive" , "Voluptuous" , "Erotic" .)
