TIT (today i teach): you can use https://www.urbandictionary.com/ to explain new words of phrases.
in firefox (and many other browsers too), you can right click the search bar and “add search engine”, and you can add a “keyword”, i personally use “ud”, and then i can type “ud dni” (for instance) in the address bar (ctrl+l to get there quick) and it goes straight to results

if the page isn’t supported, it doesn’t show “add search engine”, google translate for example, you can still add it in a different way
search for a recognisable word, and bookmark the resulting page. then go to bookmark/manage bookmarks (ctrl+shift+o), find the bookmark, replace your recognisable word with “%s”, add a keyword (depending on the language i use 2en, 2de, 2jp etc)
