In colloquial English (particularly in online discourse) the phrase "in my opinion" (often abbreviated as "imo/IMO") is quite common. I am wondering how one might express this in an idiomatic manner in Latin.
One could take the completely literal approach and simply write:
in meā sententīa, in sententiā meā, meā sententiā, vel sententiā meā
But my gut feeling tells me that the above would either (a) be intelligible to a Roman, but feel unnatural and unidiomatic or (b) be completely unintelligible to a Roman, and perhaps even ungrammatical.
In short: how would one express the English phrase "in my opinion" idiomatically, in Latin?
