Yesterday, I wanted to fry some fish. To do this properly, I needed flour. So I went to my friend downstairs and asked, “můžu pučit moucha?” She laughed. “Máš pavouka?” Why would she ask me if I had a spider. I tried again, and she laughed again. Then she explained to me that I was asking for a bug. To my ears there is very little difference between the “ch” and “k” sounds of Czech. But when I try to borrow flour again, I’ll be sure to ask for “mouka”.
