passaged
- 1Simple past tense and past participle of passage.
Researchers passaged the virus repeatedly to weaken it for the vaccine.
The horse had passaged elegantly down the centerline before the judges.
Note
A regular form: the single -ed spelling serves as both past tense and participle (researchers passaged the virus; the horse had passaged). Its uses split by field and by grammar. In the laboratory it is transitive, and you passage a pathogen or stem cell through a host or medium. In horsemanship it is intransitive, because the horse itself executes the passage movement. Using it to mean crossing by sea is rare.
