I often hear in Russian an expression that I suppose can be translated as "I swear it", or "I give you my word". I hear something as "часно слово", "час на слово" ?
What is its right spelling and what does it exactly mean?
Remark: I cannot find it in lingvo, wikipedia, gramota nor by translation, even trying with combinations of possible spelling mistakes (exchanging ч by ш, the о's by a's, итд.)
Edit: of course, my ear can just be unmature to hear Russian and detect all possible spellings .
