Nasal problem? Suggestion is provided about one after runs (8)
I believe the answer is:
rhinitis
'nasal problem?' is the definition.
'suggestion is provided about one after runs' is the wordplay.
'suggestion' becomes 'hint' (hint is a kind of suggestion**).
'provided about' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'after' says to put letters next to each other.
'runs' becomes 'r' (cricket abbreviation).
'hint'+'is'='hintis'
'hintis' going around 'i' is 'hinitis'.
'hinitis' after 'r' is 'RHINITIS'.
(Other definitions for rhinitis that I've seen before include "trouble with the beak" , "nasal affliction" , "I hint, sir, about a nose inflammation" , "Inflammation of the lining of the nose" , "Nasal inflammation" .)
