Destined fatefully to confuse me with the dodo (6)
I believe the answer is:
doomed
'destined fatefully' is the definition.
'doomed' can be an answer for 'destined' ('doom' can be a synonym of 'destine'). I am not certain of the 'fatefully' bit.
'confuse me with the dodo' is the wordplay.
'confuse' is an anagram indicator.
'with' says to put letters next to each other.
'me' after 'dodo' is 'dodome'.
'dodome' anagrammed gives 'DOOMED'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for doomed that I've seen before include "Damned or condemned" , "Condemned to destruction" , "Condemned to failure" , "Fated" , "Consigned or sentenced to hell" .)
