Exponentially → It is formed from "ex-" (meaning out of or from) and "ponere" (meaning to place or put), combined with the suffix "-ially" (meaning in a manner relating to). The word "exponentially" refers to a manner of growth that is out of or from a base that increases rapidly, often in a mathematical context.
Think of something growing 'out of' ('ex-') a base that is 'placed' ('ponere') in a way that causes it to increase rapidly. This helps you remember that 'exponentially' describes a very fast rate of growth.
