Located in front of or above the central line of the body or a specific body part.
The preaxial region of the limb is important for understanding its development.
Preaxial is formed from "pre-" (meaning before) and "axial" (from Latin "axis", meaning axis or line). The term refers to something that is situated before or in front of the axis.
Think of 'pre-' meaning 'before' and 'axial' relating to an 'axis' — so preaxial describes something that is located before the axis.
