Co to je?
What is this?
'Co' originates from the Old Czech 'co', which is a pronoun with roots in Proto-Slavic '*čьto', meaning 'what.' It has remained an essential interrogative word in the language.
'Co' is used in everyday spoken and written Czech to ask questions about objects, actions, or concepts. It is informal in register but widely accepted in both written and spoken forms.
