When the stem (or root)
of a verb ends in a vowel (excluding "u" and "i") and
the ending begins with a vowel, contraction of the vowels often takes place.
- Verb stems must end
in a, e, or o.
- 'O' dominates over
'A' or 'E'; 'A' dominates over 'E.'
- 'I' in the ending is
- Omicron or epsilon,
combined with omicron or epsilon, form a diphthong.
- A diphthong remains
- A long vowel remains
a long vowel.
The stem must end in a,
e, or o (the three vowels in the word 'CONTRACTED.' The
vowels will dominate over each other in the order that they appear in the
word 'contracted': thus 'O' sound over 'A' and 'E' and 'A' sound over 'E.'
Think of the two poles
of a magnet. Two likes repel. So with Greek vowels and consonants. Often
when two vowels or two consonants come together when an ending is added
to the stem of a verb, vowel contraction or consonant modification is required.
