Word origin
Two etymologically distinct words: 'polish' the verb /ˈpɒlɪʃ/ ('to make shiny') is from Old French polir, from Latin polīre ('to polish, finish'). 'Polish' the adjective /ˈpoʊlɪʃ/ ('from Poland') is from 'Pole' + the adjectival suffix '-ish'. The two words are unrelated — they share spelling because of an accident of how Latin -is- and Germanic -ish- happened to converge in Middle English orthography.
Fun fact
The 'polish vs Polish' is a classic capitalization-determines-pronunciation case in English. The same letters spell two completely unrelated words — 'polish' (lowercase, from Latin polīre) means 'to shine,' while 'Polish' (capitalized, from 'Pole' + '-ish') means 'from Poland.' Most heteronyms are pronounced differently regardless of capitalization, but 'polish/Polish' is one where capital letters carry phonetic weight.
