Figure welcoming fine faculty (8)
I believe the answer is:
eyesight
'faculty' is the definition.
(eyesight is a kind of faculty)
'figure welcoming fine' is the wordplay.
'figure' becomes 'eight' (I've seen this in other clues).
'welcoming' means one lot of letters goes inside another (in sense of 'inviting in').
'fine' becomes 'yes' ('fine' is a way of saying 'yes').
'eight' going around 'yes' is 'EYESIGHT'.
(Other definitions for eyesight that I've seen before include "Power of seeing" , "Requirement to look" , "quality of viewing" , "Perceptive faculty" , "Seeing faculty" .)
