Mary, I just noticed this thread and it looks as though you already have your answer but, for the record, I agree with M. Ted; It's an eleventh chord. Never mind that the third and seventh are missing. Most modern chords on guitar turn out to be partial chords, usually some inversion other than the theoretical spelling.

I think from now on I'll just ask M. Ted directly about questions of theory. His explanation is great. I nominate M. Ted as official Mudcat Theoretician.
