Morphology

ablative = ablate (semi-transparent) = ablate + ive

Formed from the verb 'ablate' + suffix '-ive', so the adjective meaning 'designed to be removed by ablation' is predictable for learners familiar with the technical verb but may be opaque to general learners.

Etymology

Ablative (material) also comes from Latin ab- 'away' and ablatus 'carried away', so an ablative coating is made to 'burn away' and carry heat away from the thing it protects.
