Two senses of 奠: to firmly establish, as in 奠定 (to lay a foundation) and 奠基 (to lay a cornerstone); and to make a funeral offering, as in 祭奠 (to hold a memorial).
酋 on top is a jar of wine. The character pictures wine set down as an offering, the source of both 'to make an offering' and, by extension, 'to set firmly in place'.
