There is a method to the madness:

-d is disk (instance store)

-a is amd

-ad is both

-n is enhanced networking (ENA, or EFA on the biggest instances)

Hey thanks that is simpler than expected!

Still, apart from the obvious ones (m, c, t) there's also the myriad top-level classes that I'd have no idea about - like what is r, i, d, x, p, g etc. My brain is too puny for all that!

These are my mnemonics, pretty sure I'm not too far off though:

  r = RAM.    Instances are biased toward having more memory.
  i = I/O.    ... have fast SSDs.
  d = DISK.   ... lots of disk space.
  x = XL.     ... lots of RAM
  g = GPU.    ... have GPU hardware
...and of course now I realize this is already answered on SO. I'm keeping mine though.

This is definitely helpful, though I think the SO question showcases fairly well why someone would want the summary on the web page: Several are ambiguous and if you're not regularly exploring new instance types you're going to forget this or fall behind in your awareness of new types.
