binasal
|bi-na-sal|
/baɪˈneɪzəl/
relating to both nostrils / both nasal sides
Etymology
'binasal' originates from Latin, specifically from the prefix 'bi-' and the adjective 'nasalis' (from 'nasus'), where 'bi-' meant 'two' and 'nasus' meant 'nose'.
'binasal' is formed by combining Latin elements: the prefix 'bi-' (from Latin 'bis', 'twice') with 'nasalis' (from Latin 'nasus' meaning 'nose'); the component 'nasal' entered English via Medieval/Old French and Middle English as 'nasal'.
Initially it literally meant 'having or relating to two noses/nostrils' and over time it has come to mean 'relating to both nostrils' or more broadly 'pertaining to the nasal sides (e.g., of the visual field) in both organs'.
