Odd male entertaining a European that is very bright (5,4)
I believe the answer is:
laser beam
'that is very bright' is the definition.
(a laser beam is very bright)
'odd male entertaining a european' is the wordplay.
'odd' indicates anagramming the letters.
'entertaining' indicates putting letters inside.
'european' becomes 'serb' (person from Serbia).
'male' with letters rearranged gives 'leam'.
'a'+'serb'='aserb'
'leam' placed around 'aserb' is 'LASER BEAM'.
(Other definitions for laser beam that I've seen before include "Shaft of light or electro-mechanic radiation" , "penetrating light" , "Shaft of light or electromagnetic radiation" , "Column of intensified light" , "Intense ray of light" .)
