Unobtrusively 'discovered' another oddball heading Question Time (2,3,2)
I believe the answer is:
on the qt
'unobtrusively' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'discovered another oddball heading question time' is the wordplay.
'discovered' indicates the central letters (dis-covered - outer letters removed).
'oddball' indicates anagramming the letters.
'heading' is a charade indicator (letters next to each other) (some letters go in front of or head others).
'question' becomes 'q'.
'time' becomes 't' (abbreviation).
The central letters of 'another' are 'nothe'.
'nothe' is an anagram of 'onthe'.
'onthe'+'q'+'t'='ON THE QT'
Can you help me to learn more?
(Other definitions for on the qt that I've seen before include "In secret, not openly" , "Secretly" .)
