IPA: /əˈbæks.i.əl/
KK: /əˈbæk.si.əl/
This word describes something that is positioned away from the central line or axis of an object, such as a plant or body part.
The abaxial surface of the leaf is often where the stomata are located.
Abaxial is formed from "ab-" (meaning away from) and "axial" (from Latin "axis", meaning axis or central line). The term describes something that is situated away from the axis, particularly in botanical contexts where it refers to the side of a leaf that is away from the stem.
Think of 'away from' ('ab-') the 'central line' ('axial') to remember that 'abaxial' refers to something positioned away from the axis.
