Etymology
The word 'palatal' has a direct anatomical lineage from Latin. Its core component, 'palat-', derives from the Latin 'palatum', which specifically referred to the roof of the mouth. This term was adopted into Middle English via Old French. The suffix '-al', of Latin origin through French, is a standard adjectival formative meaning 'relating to'. Thus, the literal construction 'relating to the palate' accurately describes both the anatomical and, by 18th-century extension, the phonetic sense, where sounds are classified by the tongue's contact point with this part of the mouth.
Analysis
'palat' originates from the Latin 'palatum', meaning 'the roof of the mouth'. '-al' is a Latin-derived suffix used to form adjectives meaning 'of or pertaining to'.
