Relating to, causing, or characterized by congelation; having the property of causing something to freeze or solidify.
From Latin 'congelativus,' formed from 'congelatio' + the adjective suffix '-tive,' meaning 'tending to' or 'relating to.'
Congelative is a technical adjective you'd find in scientific papers discussing freezing processes, but it's so specialized that even many educated people wouldn't recognize it.
