Is in a tizz on an Egyptian peninsula (5)
I believe the answer is:
sinai
'an egyptian peninsula' is the definition.
(I've seen this in another clue)
'is in a tizz' is the wordplay.
'is in a' anagrams to 'SINAI'.
But, I'm not clear how the anagram is indicated.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for sinai that I've seen before include "One showing genetic change" , "desert area" , "Mount on which Moses received the Ten Commandments" , "Biblical mount" , "Deserted area" .)
