Etymology
IAA stands for indole-3-acetic acid, a plant hormone that helps stems and roots grow. The name shows its parts: acetic is the same root seen in 'vinegar', so it tells you this is an 'acid', and indole names a part of the molecule, so IAA is just a short way to refer to that growth-making acid.
