Using sense, considering (6)
I believe the answer is:
seeing
This could be a double definition.
'using sense' is the first definition.
'seeing' can be an answer for 'sense' (seeing is a kind of sense). I'm unsure of the 'using' bit.
'considering' is the second definition.
('see' can be a synonym of 'consider')
Can you help me to learn more?
(Other definitions for seeing that I've seen before include "Spotting - interviewing" , "Noticing" , "... is believing, it's said" , "Watching" , "Meeting" .)
