Present participle of fulcrum used as a verb; the act of providing support or using as a lever.
From 'fulcrum' with the '-ing' gerund suffix, though the construction is archaic and rarely used in contemporary English.
This word demonstrates English's flexibility in verb formation—almost any noun can theoretically become a verb with '-ing,' but just because you CAN say 'fulcruming' doesn't mean anyone actually does in real conversation.
