The word 逆立ち (さかだち) is formed from the kanji 逆 (gyaku) which means "reverse" or "upside down," and 立 (tachi) meaning "to stand". So, literally, it means "reverse standing" or "standing upside down." The reading is a compound of the on'yomi (Chinese-derived reading) of the first kanji and the kun'yomi (Japanese native reading) of the second kanji.
