  tap, tapped, tapping
  fan, fanned, fanning
  gum, gummed, gumming
  sum, summed, summing
  drum, drummed, drumming
  trim, trimmed, trimming
  slim, slimmed, slimming
  grin, grinned, grinning
  cram, crammed, cramming
  slam, slammed, slamming
  lob, lobbed, lobbing
  grab, grabbed, grabbing
  trip, tripped, tripping

A single consonant after a single vowel.

In BE we also double the final 'l' in two syllable words, like 'travelling', but our American friends don't follow suit.

12) be being

This is very rarely used. Yo u will occasionally hear 'He will be being picked up at this very moment', but it is an uncomfortable usage and we tend to avoid it. The same is true of 'been being'.

  sad, sadder, saddest
  tan, tanner, tannest
  dun, dunner, dunnest
  glum, glummer, glummest
  slim, slimmer, slimmest
  trim, trimmer, trimmest
  thin, thinner, thinnest
