Elongation

All words can be written with any number of consecutive vowels or consonants and still be correct. For instance, the English word ladder:

• laedyr / ly'dyr (no specific emphasis when spoken)
• laeddyr / ly'ddyr (emphasize the 'd' sound)
• laedddyr / ly'dddyr (really emphasize the 'd' sound)
• laeedyr (drawn out 'a' sound)
• laeeedyr (really drawn out 'a' sound)
• laedyrr / ly'dyrr (drawn out 'r' sound)
• laedyrrr / ly'dyrrr (really drawn out 'r' sound)
• ly'dieer (drawn out 'e' sound)
• ly'dieeer (really drawn out 'e' sound)

This can be useful for indicating tone. The vowels with must be written in their two letter form if they have one.
