Comprehend meaning (5)
I believe the answer is:
sense
This clue is a double definition.
'comprehend' is the first definition.
(I know this)
'meaning' is the second definition.
(I know that meaning can be written as sense)
(Other definitions for sense that I've seen before include "Inward feeling" , "Perceptual faculty" , "Awareness" , "definition" , "Logic" .)
