Combinations of vowels

ae ea ai ia ao oa au ua ay ya

ei ie eo oe eu ue ey ye

io oi iu ui iy yi

ou uo oy yo

My suspicion is that if any of these combinations occurs in a syllable of a word, one letter has a fair chance of becoming silent. I may look into it soon to see if I can find a general set of rules.

Stay tuned
