parse vt. 1. To determine the syntactic structure of a sentence or other utterance (close to the standard English meaning). That was the one I saw you. I can't parse that. 2. More generally, to understand or comprehend. It's very simple; you just kretch the glims and then aos the zotz. I can't parse that. 3. Of fish, to have to remove the bones yourself. I object to parsing fish , means I don't want to get a whole fish, but a sliced one is okay. A parsed fish has been deboned. There is some controversy over whether unparsed should mean bony , or also mean deboned.
