'vasospasmic' originates from English, specifically formed from the noun 'vasospasm' plus the adjectival suffix '-ic', where the combining form 'vaso-' comes from Latin 'vas' meaning 'vessel' and 'spasm' comes from Greek 'spasmos' meaning 'a drawing or spasm'.

'vasospasmic' was created by adding the suffix '-ic' to the noun 'vasospasm' (itself coined from Latin 'vas' + Greek 'spasmos') in modern English to form an adjective meaning 'relating to vasospasm'.

Initially it named phenomena related to 'vasospasm' (the vessel spasm itself); over time the formed adjective came to be used more generally to describe conditions, responses, or features characterized by vasospasm.
