Getting a letter wrong in the second half of the alphabet (4)
I believe the answer is:
beta
'second half of the alphabet' is the definition.
'beta' can be an answer for 'second' (second Greek letter). I am unsure of the 'half of the alphabet' bit.
'getting a letter wrong in the' is the wordplay.
'getting' says to put letters next to each other.
'letter wrong in' becomes 'be' (I can't explain this - if you can you should believe this answer much more).
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'be'+'t'='bet'
'a' put after 'bet' is 'BETA'.
Can you help me to learn more?
(Other definitions for beta that I've seen before include "Greek character - not quite top-notch" , "Character between alpha and gamma" , "Second-rate" , "character in Marathon" , "testing stage" .)
