Help using [dict] to get Oxford Dictionary API data

I'm having trouble getting data that is returned from the Oxford Dictionary API. I seem to be misunderstanding how to use 'get' messages to [dict] to get data in lists, which are marked in brackets -- [ ]. The example patch shows how I can access some data as expected but not other data inside lists, such as "definitions".

Here's a link to the Oxford Dictionary documentation: https://developer.oxforddictionaries.com/documentation
Pretty cool stuff. I'm wondering if anyone knows how I need to format my 'get' messages to access this data? I'm not finding anything in the documentation or forum that addresses this specific question. Thanks for any help!
