Concerning current opinion in Lebanon, somewhat taken aback? (2,4)
I believe the answer is:
el nino
'concerning current' is the definition.
'el nino' can be an answer for 'current' (I've seen this before). I'm not sure about the 'concerning' bit.
'opinion in lebanon somewhat taken aback?' is the wordplay.
'somewhat' indicates a hidden word.
'taken aback?' is a reversal indicator.
'oninle' is hidden in the letters of 'opinion in lebanon'.
'oninle' backwards is 'EL NINO'.
Can you help me to learn more?
(Other definitions for el nino that I've seen before include "Pacific climatic effect" , "Pacific climate effect" , "Pacific climate pattern" , "Area of hot water and air in the Pacific at Christmastime" , "Warming Pacific current" .)
