Ablaqueation, (æbləkweɪʃən), is a rarely used word that refers to the process of washing or cleaning by using water. The word is derived from Latin, where "abl" means "off" and "aque" refers to "water." The pronunciation of this word can be quite tricky due to the combination of multiple consonants, including the "bl" and "qu" sounds. Nevertheless, mastering this tongue-twister of a term could certainly impress your friends and colleagues in a game of Scrabble.
