I thought this might be the present passive of proficio but this verb has no passive so I looked at the paradigms of similar verbs but no luck. What verb does it belong to? Is it a syncopated form?
It is the present infinitive passive of proficio.
This is what I thought at first but I consulted wiki but wiki said this verb has no passive forms. I guess wiki is not so reliable.
Try logeion instead, which has also a morphological tool.
Yeah, it’s not. Think of it as a largely unfinished but constantly improving work (even if its improvements sometimes come about slowly).
See OLD proficio, definition 1b: proficio used in the impersonal passive. Note that a number of intransitive verbs are used in the impersonal passive.
The OLD’s first exemplary quote is from Cicero Sest. 60 (Pro Sestio) which shows a use of the passive infinitive profici as impersonal with aliquid as subject accusative.
_M. Cato, etiam cum iam desperasset aliquid auctoritate sua profici posse,_Marcus Cato, even now when he had already despaired that anything was able to be done upon
his own authority…
