You see the word. You don't understand it. You double click it. Now you do [understand it and go ahead].
That's pretty much the whole usage pattern for a new Google Chrome extension — Google Dictionary, offered, surprisingly, by Google itself. Well, it's not your average dictionary, it looks just a bit more sleek and fun, explaining things in a language which is likely to be understand by someone who doesn't have a PhD in English literature; well, it works for me. Take a look yourself if you're like me — not feeling entirely confident in a grim and dangerous world of irregular verbs, past perfect tenses and their ilk; or again, may be you're just curious. Take a look anyway.
