I goes into too much detail for a dictionary entry...
Who says it has to be telegraph style? Wouldn't an encyclopedia-like entry do?

I'd feel a lot better about both E and I if not for the other...two near-identicals = both red herrings, scuttle the lot of 'em, says I. That goes for H, too. Unfortunately that also eliminates A and M, likewise B and J and K, E and F. Leaving only C, D, and L...

And then this was in today's newspaper, picked up by the Associated Press:

Gotta pick M. Even though I want it to be I.
