Every now and then I see a reference to positions of someone referred to as "The Rav". Typically a person refers to his own Rosh Yeshiva as such. But normally others would have an idea who his R"Y is, as such they would know who he is referring to. As I read some online postings I noticed some people uses this term to refer to someone even though others didn't know who they are referring to. So I thought perhaps they are referring to the Brisker Rov, Reb Velvel, who was universally known simply as "The Rov" while he was still the Rov in Brisk (as his father was known before him) and was continually known as such when he moved to Eretz Yisroel. I thought perhaps "The Rav" was an anglicized rendering of the The Rov.
But I saw positions attributed to "The Rav" that clearly could not be coming from The Rov. So after googling a bit I realized they were referring to Rav Yoshe Ber Soloveitchik of America, a nephew of The Rov. Apparently his students titled him as his illustrious uncle, in recognition of his Brisk heritage. It seems to me at least that this breeds confusion. Should not he be referred to with a differential than as his Uncle was? (I believe the subsequent Brisker Rov's are also known as The Rov.)
