Sight possibly seen at the bus terminus? (5)
I believe the answer is:
sense
'the bus terminus?' is the definition.
The definition and answer can be both related to thinking as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'sight possibly seen' is the wordplay.
'sight' becomes 's' (this might be a standard abbreviation of which I'm unaware).
'possibly' indicates anagramming the letters.
'seen' is an anagram of 'ense'.
's'+'ense'='SENSE'
'at' is the link.
Can you help me to learn more?
(Other definitions for sense that I've seen before include "Get an impression" , "Feeling or faculty" , "Sound practical judgment" , "Could be hearing" , "Realistic attitude" .)
