Leader of Turkey that is welcoming outsiders in loud foreign accent (5)
I believe the answer is:
tilde
'foreign accent' is the definition.
'tilde' can be an answer for 'accent' (I've seen this before). I am not sure about the 'foreign' bit.
'leader of turkey that is welcoming outsiders in loud' is the wordplay.
'leader of' says to take the initial letters.
'that is' becomes 'ie' (abbreviation for id est, 'that is' in Latin).
'welcoming' means one lot of letters goes inside another (in sense of 'inviting in').
'outsiders in' means to remove the middle letters.
'loud' with its centre removed is 'ld'.
The first letter of 'turkey' is 't'.
'ie' placed around 'ld' is 'ilde'.
't'+'ilde'='TILDE'
Can you help me to learn more?
(Other definitions for tilde that I've seen before include "Spanish cedilla" , "Diacritical mark over a letter thus, n" , "part of Sao Paulo, originally" , "what Spanish writing requires" , "Spanish accent, as in se-or, ma-ana etc." .)
