navi1-2  Exercise 2: Possible Syllable Starts
=============================================

The rule: a two-consonant start must begin with f, s or ts, followed by one of
p t k px tx kx m n ng r l w y.

  (a) fp    possible   f + p
  (b) sk    possible   s + k
  (c) tsk   possible   ts + k (ts counts as one consonant)
  (d) ps    NOT possible   it does not begin with f, s or ts; also s may only
                           START a syllable, so it cannot come second
  (e) bt    NOT possible   Na'vi has no b; and b is not one of f, s, ts
  (f) fng   possible   f + ng (ng is one consonant)

Note: (c) and (f) look long in English spelling but are still only two
consonants each, because ts and ng are single sounds.
