asseoir

The word for "sit" in all Indo-European languages comes from the same source, Proto-Indo-European *sed-: Spanish sentar(se), French (s')asseoir, Russian sadit'(sya), German "sitzen" and English "sit," "set," "seat." The verb in Latin was "sedere," the past participle of which is "sessus." Latin sessilis "sitting down, stunted," whence today's word, was based on the participle. You might think that "chair" would be related to this root—and you would be right. The [s] became an [h] in Greek (remember Latin "semi-" = Greek "hemi-"?) so, with the suffix –ra, "hedra" became "seat" in Greek. Prefixed with kat(a) "down," the direction most folks sit in, it became "cathedra," a word borrowed by Latin in the sense of "armchair, cushioned chair." (The cathedral church is the one with the bishop's cathedra or throne.) Old French hammered this word into "chaière" and we polished it down to "chair."1 fiziki
