The GfyCat URL generator list is about ~1800 animals and ~8000 adjectives [0]. All fairly memorable words. Add in other types of words and 2048 quickly becomes a small number. The words don't have to be incredibly simple, either. Grabbing a random GfyCat image from the front page gives me "OrangeLankyBasilisk" which is easy to remember, none of those words are particularly foreign. But they're not in your list of most common words, nor are any of them in XKCD's simplewriter [1], which keeps track of the 1000 most common words.

[1] https://xkcd.com/simplewriter/ https://xkcd.com/simplewriter/ Edit: The words need to be randomly chosen by a computer, so it doesn't matter what the most common words are. You could generate the password from a list of 2048 spanish words or japanese words or emojis and the entropy is the same as the previous scenario (assuming the attacker knows your dictionary of symbols just like they'd know your dictionary of English words). If you let a human choose, of course the smiley-face and poop emojis are going to be picked 50% of the time, but that's not the intention of the comic or passphrases.
