Etymology
Etymology Information

'contralateral' originates from Latin elements, specifically 'contra-' (from Latin 'contra') and 'lateralis' (from Latin 'latus'), where 'contra-' meant 'against, opposite' and 'latus' meant 'side'.

Historical Evolution

'contralateral' was formed in New/medical Latin as 'contralateralis' (combining 'contra-' + 'lateralis') and was adopted into modern English with the same form and meaning.

Initially it meant 'on or toward the opposite side' and over time has retained this specialized anatomical/neurobiological meaning.
