To A-Sam,
In Hakka the most significant vocabulary distinguishing Hakka from neighbouring dialects is the pronouns
I = ngai /Nai11/
you = ngi /Ni11/
he/she/it = gi /ki11/
These should be in the same tone, though in my dialect, it is a low level tone signified by beginning and end points /11/.
In my dialect, possessive pronouns are in a slightly different tone, a mid level tone /33/
my = nga /Na33/
your = ngia /Nia33/
their = gia /kia33/
Other indicators of a Hakka dialect include the way you say "what"
what = mak gai /mak3 kai53/
/mak3/ is a mid level pitch in my dialect. In others, it is a low pitch /1/ or possibly /2/
/kai53/ in my dialect is a high falling pitch, signified by the high starting point /5/ and falling to about mid pitch range /3/
I notice that Hakka call schools hok tong /hok5 t'ON11/ where /hok5/ is in the high pitch intonation, and /t'ong11/ is in a low one.
My family is from Hong Kong, which we pronounce as hiong gong /hiON33 koN31/, with the first syllable if you pronounce it by itself is in a mid level intonation. The latter syllable is a mid falling tone /31/.
All these words and syllables illustrate the six tones in my dialect of Hakka. Traditionally, they are ordered as follows
tone 1 (yim pin /jim33 p'in11/) /33/
tone 2 (yong pin /jON11 p'in11/ ) /11/
tone 3 (shang sang /sON53 saN33/) /31/
tone 4 (hi sang /hi53 saN33/) /53/
tone 5 (yim ngip /jim33 Nip5/) /3/
tone 6 (yong ngip /jON11 Nip5/) /5/
so I can write ngai2, ngi2, gi2, nga1, ngia1, gia1, mak5 gai4, hok6 tong2, hiong1 gong3, in the romanisation I've cobbled together for Hong Kong Hakka. I'm not saying all Hakka dialects are similar to mine, especially in intonation, but if you look in my site, you'll find that the tone system varies across the Hakka populated areas of Southern China from systems which have as few as five tones to some which have as many as seven or eight or more.

Thomas Chin has a similar list of tones for Hakka somewhere on this site (chineselanguage.org) too.
I'm currently making a wordlist/dictionary of Hakka words and English meanings which I've temporarily located here
http://www.dylanwhs.ukgateway.net/dict/index.html
so far I've only got 2100 or so entries. Its finding the time to put in newer entries. Luckily, with the help of a bit of programming, I can almost instantly convert my list into separate HTML files for entries which begin with the same few letters.
Cheers,
Dyl.
