Mongolian warrior giving thanks to sailor (5)
I believe the answer is:
tatar
'mongolian warrior' is the definition.
'tatar' can be an answer for 'warrior' (I have seen 'Mongol warrior' mean 'tatar' so perhaps 'warrior' could also mean 'tatar'). I am not certain of the 'mongolian' bit.
'giving thanks to sailor' is the wordplay.
'giving' is a charade indicator (letters next to each other).
'thanks' becomes 'ta' (UK informal version of 'thank you').
'to sailor' becomes 'tar' (tar is a kind of sailor).
'ta' next to 'tar' is 'TATAR'.
Can you help me to learn more?
(Other definitions for tatar that I've seen before include "Asian" , "Turkic language" , "One of a people from Russia and Ukraine" , "Mongol warrior" , "Russian" .)
