Regularly uncertain about dodgy refit for African Queen (9)
I believe the answer is:
nefertiti
'african queen' is the definition.
(I've seen this before)
'regularly uncertain about dodgy refit' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'about' is an insertion indicator.
'dodgy' indicates an anagram.
The alternating letters of 'uncertain' are 'neti'.
'refit' anagrammed gives 'ferti'.
'neti' going around 'ferti' is 'NEFERTITI'.
'for' acts as a link.
(Other definitions for nefertiti that I've seen before include "Oddly, the Egyptian queen is an entire fit" , "old queen" , "Name of queen" , "Egyptian beauty queen" , "Egyptian queen, the wife of Akhenaton" .)
