Etymology
The word 'ocular' has a direct lineage from Latin, where oculus meant 'eye'. This Latin term itself is traced back to the Proto-Indo-European root okʷ-, which meant 'to see' and is the ancestor of numerous words related to sight across Indo-European languages. The suffix '-ar', also of Latin origin (-aris), is commonly attached to nouns to form descriptive adjectives. Therefore, the literal construction 'of or pertaining to the eye' has remained semantically stable, evolving into its modern English usage to describe anything related to vision or the physical organ of sight.
Analysis
Structure: ocul (eye) + ar (adjective suffix)
