Faith has short fling with head of college in Switzerland
I believe the answer is:
church
'faith' is the definition.
(synonyms)
'short fling with head of college in switzerland' is the wordplay.
'short fling with' becomes 'hur' (I can't explain this - if you can you should believe this answer much more).
'head of' indicates taking the first letters.
'in' is an insertion indicator.
'switzerland' becomes 'ch' (short for Confoederatio Helvetica, its Latin name).
The first letter of 'college' is 'c'.
'hur'+'c'='hurc'
'hurc' going inside 'ch' is 'CHURCH'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for church that I've seen before include "See 1" , "See 11" , "Body professing common creed" , "Building for religious worship" , "A building for Christian worship" .)
