Morphology

gilgai + soil

The element 'gilgai' is a specialized, region-specific geomorphological term (of Aboriginal/Australian origin) that is not analyzable from general English vocabulary, so knowing 'soil' only yields that this is a type of soil but not its properties. Because the key lexical item is opaque to typical learners and the overall meaning is technical rather than compositionally derived, the expression is not predictable from its parts.

Etymology

Gilgai soil comes from an Aboriginal word gilgai meaning 'small waterholes' or pits that form in clay when it swells and shrinks. Those little hollows and raised mounds make the ground very uneven, so gilgai soil means soil with these bumpy dips and mounds.
