Aliyot is in Webster's ; defined as the action of going up or being called to the reading desk of the synagogue to read from the scriptures. there is no alternative aliyat given.
it also means going from the Diaspora to live in Israel...literally ascending to live there. The chalutzim were the "pioneers" of the late 19th & early 20th Centuries who left E. Europe to flee pogroms/anti-semitism and make a new life in then Palestine to "make the desert bloom"
