Hi,
It is complicated. I've yet to see a wholly lucid explanation. But here's a simplified condensation of the several sources I've read (Beekes, Palmer, Sihler).
Ancient greek shows two different systems of vowel alternation (ablaut). The more familiar one is the variation between
e,o,0 (where zero means the vowel is completely lost)
An example in greek of this ablaut sequence is
[face=SPIonic]lei/pw, le/loipa, e)/lipon[/face]
The less familiar system shows alternation between several sets of long vowels, e.g.,
long e, long o, e (where the last e represents the zero grade)
An example in greek of this ablaut sequence is
[face=SPIonic]ti/qhmi, qwmo/j, qeto/j[/face]
This leads to table of ablaut relations as shown below (this table also shows the other two long vowel ablaut sequences).
e, o, 0
long e, long o, e
long a, long o, a
long o, long o, o
Seeking to simplify this system, Saussure suggested that perhaps the long versions of the vowels were really equivalent to e
plus some other entity. That is:
long e = e + ?1
long a = e + ?2
long o = e + ?3
This suggestion simplified the greek ablaut system by basing it on the single, commoner ablaut sequence. A table of this simplified system
looks like this:
e, o, 0
eE, oE, E
eA, oA, A
eO, oO, O
Saussure called these entities (E,A,O) 'coefficients sonantiques'. They later came to be called schwas; then laryngeals (written H1, H2, H3).
Whatever they are called, some of their effects in greek are:
Before a vowel - a laryngeal disappears but not before coloring the vowel. Examples:
H1e > [face=SPIonic]e[/face]
H2e > [face=SPIonic]a[/face]
H3e > [face=SPIonic]o[/face]
whence
[face=SPIonic]e)/dw[/face] < *H1ed-
[face=SPIonic]a)/gw[/face] < *H2eg-
Before a consonant at the start of a word - a laryngeal becomes a 'prothetic' vowel, and these vowels retain the character of
their original laryngeal. Examples:
[face=SPIonic]a)me/lgw[/face] < *H2melg-
[face=SPIonic]o)re/gw[/face] < *H3reg-
In vowel, laryngeal, consonant (VHC) sequences - a laryngeal disappears but colors and lengthens the vowel. Examples:
[face=SPIonic]ti/qhmi[/face] < *dhi-dheH1-mi
[face=SPIonic]i(/stami[/face] < *si-steH2-mi
[face=SPIonic]di/dwmi[/face] < *di-dheH3-mi
I hope this helps.
Cordially,
Paul
