talmacasta

adjective. upside down, *topsy-turvy, head over foot

A neologism for “upside down” coined by Tamas Ferencz, a combination of Q. talma “base” with Q. cas(ta) “upwards”. I would limit this word to extreme or abnormal inversions, such as “topsy-turvy” or “head over foot”. For more ordinary vertical reversals I would use attested nuquerna “reversed, inverted”.
