Benjamin Zimmer at Language Log has a fascinating post on “the speech patterns of northeastern Pennsylvania,” taking off from a YouTube video called “Heynabonics,” heyna or haina being apparently a tag question characteristic of the region:
Putting haina on the end of a statement makes the statement a question. It doesn’t matter who you’re talking to, or when the thing happened. “You’re going dancing Friday night, haina?” means “Are you going dancing Friday night?” “He did that last night, haina?” means “Did he do that last night?”
There are interesting parallels with (and possible influences from) Pennsylvania Dutch and Hindi, not to mention British innit. Well worth your attention.
