I _think_ it originally stood for "Ethereal tree type". The first
implementation used a set of #defines in packet.h, like so from revision 2:

/* Tree types.  Each dissect_* routine should have one for each
   add_subtree() call. */

#define ETT_IEEE8023      0
#define ETT_ETHER2        1
#define ETT_LLC           2
#define ETT_TOKEN_RING    3
  [ ... ]

I think "expansion tree type" is a much better definition.
