How to "undo" a download within an app


Android Question

I was looking at the "Quick Translator" app that came on my new LG G2 phone, and was scrolling through the amazing list of languages and downloadable dictionaries it has, when the phone misinterpreted one of my scrolling flicks as a tap. Before I could react, it downloaded a dictionary that I really don't want.

Unfortunately, this app allows you one free dictionary download, and then requires you to pay for any additional ones. I hate to waste my free one on something I am unlikely to ever use. I cannot find a way to uninstall this dictionary. Can anyone advise how to do it? Thanks!
