Morphology
basilar = basal (transparent) = basi + ar
The adjective is directly formed from the base notion of 'basal/base' with the productive adjective-forming suffix '-ar', so learners who know 'base' or 'basal' can infer the meaning.
Etymology
Basilar comes from the old word basis, which means 'base' or 'foundation' and is like the English words base and basement. So basilar means 'at the base' of a part or structure, for example the basilar artery at the base of the brain.
