In yesterday’s posting on “Address terms in service encounters”, I looked at an unfortunate confluence of two patterns of vocatives: one in address terms used to me by some Hispanic servers at the restaurant Reposado in Palo Alto (in particular, the address term Mr. Arnold), and one in address terms used by slaves to their masters in plantation days (in particular the address form Mr. FN, as in Mr. Simon used by slaves to address their master Simon Legree) and (historically, a continuation of the slave practice to post-slavery contexts, but still involving blacks addressing whites) by employees in some parts of the South to their employers (again, the address form Mr. FN, as in Mr. Keene used by a stableman to address his employer Keene Daingerfield in Lexington KY a couple generations ago). The two address forms are formally identical, and both are used by speakers providing a service to the addressee, but the sociocultural contexts are very different, and the (inadvertent) echo of slave usage in a Mexican restaurant is unpleasant.
Now it turns out that Prefix (Mr./Miss) + FN turns up in a number of circumstances where providing services is not at issue, including some in which the form is not at root a vocative, but functions instead as a kind of professional name, which can be used referentially or vocatively. In these contexts, race is not in the mix, and there are no unfortunate echoes of slavery. Get ready for teachers of young children, psychics, and male hairdressers.
