@C.Koca Nice! :D In English it is "Pole", and Polish "Lech" (c in Polish 'ch' is silent, and thus Turkish "Leh" makes sense) is also a word, but it is rather used for our ancestors/founders rather than nowadays' people. We have some "jokes" or "anecdotes" that take place in medieval times and universally feature 3 characters: Lech, Czech and Rus.
