July 17, 2025 - Even fictionalized versions of the word, like “green-ify” (shout-out to fans of Wicked), are spelled with an “i.” But “liquefy,” meaning to make or become liquid, ends with “-efy.” To make matters even more confusing, “liquid” itself is spelled “-qui,” really making you think that second vowel should be an “i.” But nope—the fact that “liquefy” is spelled with an “e” makes it one of our hardest words to spell.

February 22, 2025 - The word has since come to mean two things: something truly wonderful or something ridiculously complicated. Meaning #1: Wonderful, great, awesome.
