passival means an archaic progressive construction in middle voice (syntactically active but semantically passive), replaced by the passive progressive in modern English. For example, "the house is building", "the meal was eating", "the trunks were carrying down" (today "the house is being built", "the meal is being eaten").
Why “passival” is a great word
A syntactically active but semantically passive progressive construction, now archaic, in which the subject of the verb is logically the thing acted upon. From Latin passīvus ("passive") + the English suffix -al, likely formed by analogy with words like adjectival; first attested in 1879. Unlike the modern passive progressive ("the house is being built"), which explicitly marks its passivity with an auxiliary verb, or the middle voice, which implies the subject acts upon itself, the passival presented an active facade for a passive reality. It is the strange, suspended grammar of a world in transition: the dinner is preparing, the book is printing, the road is mending—a fleeting linguistic hesitation where the object of an action politely, and impossibly, pretended to be its own subject. The passival faded not from confusion but from precision's triumph, surviving now only as a faint architectural trace in phrases we no longer hear as strange.
Etymology
Probably from Classical Latin passīvus + -al, after adjectival, nominal, etc. By surface analysis, passive (noun) + -al.
