Morphology
The term is directly compositional: 'axile' means attached to or occurring around an axis and 'placentation' denotes the pattern/placement of ovules, so the phrase literally describes ovules attached around the central axis of a compound ovary. Although technical vocabulary, the overall meaning follows straightforwardly from the constituent parts and would be understandable to a learner who knows both component terms.
Etymology
Axile placentation describes a flower or fruit where the seeds, called 'ovules', are attached around a central axis inside the ovary, like sections on a middle column. So the name, with axile meaning 'axis' and placentation meaning how seeds are placed, shows the seeds are 'placed on the axis', which is the sense used today.
