puLLI mistakingly called Virama in Unicode do kills inherent a to reveal
consonant. This principle was devised because a consonant could not be
pronuounced on it's own.
The puLLI was clearly defined last in the Tamil Grammar Tolkaarpiyam about
3rd century BC. It was around for a long time.
The concept was misunderstood initially by Virama and he introuduced this
concept in Virama to other Indic languages. These are recent events, much
like Unicode introduce terms that are much confusing.
There is another concept the ancient Tamil Grammar, that is called
near-voiceless vowels, (kuTTiyal) which also defines how two consonants can
combine in an alternative fashion, in addition to reaveling the consonant.
This can be identified as u and e respectively in BuROOK and BeREAK, if we
run these speech through a speech analiser.
While on this topic, the Matrai and Matra
Matrai was originally defined as the time taken to timly modify a frequency.
It could be the time and frequency of a vowel or a consonant, remember
consonants can only be voiced with vowels. So the Matrai is crudly put it, a
timing mechanisim. For example matrai of say k and k in "kk" determines the
phonetic value of symbols(!) "kk" and similar concept is applied for ii or
What Matra is defined as in Unicode? I think Unicode think Matra dipicts
dependent vowels (or combining vowels).
Another item that breaks Tamil Unicode implementations (by wrong assumption
of Grammar) is that Auai is not acceptable. ie, long vowels are not
acceptable. I do not know where Unicode got this idea (Grammar) from but it
breaks Tamil implementations in the core. This is where I think Unicode must
forget about trying to master Grammar of all languages and find ways to let
a free run so that things can be done properly.
