Visit or contact those who seem superior? (4,2)
I believe the answer is:
look up
'visit' is the definition.
(thesaurus)
'contact those who seem superior?' is the wordplay.
I cannot really understand how this works, but
'seem' could be 'look' (synonyms) and 'look' is found within the answer.
'superior?' could be 'u' (U can mean upper-class, as in U and non-U speech) and 'u' is located in the answer.
A single letter 'p' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'or' acts as a link.
Can you help me to learn more?
(Other definitions for look up that I've seen before include "Get better" , "Search for information about, or elevate gaze" , "Gaze aloft or search for information" , "Search for information about, or go to visit" , "Check (reference); visit (friend)" .)
