Numbers
Numbers between the round thousands are made in the same way as in English; examples:
c’auq-t’aun ngà-ya ခြောက်ထောင် ငါးရာ 6500
shiq-t’aun thoùn-ya ရှစ်ထောင် သုံးရာ 8300
k’un-năt’aun lè-ya ခုနှစ်ထောင် လေးရာ 7400
hnăt’aun tăya နှစ်ထောင် တစ်ရာ 2100
hnăt’aun kò-ya ngà-zeh ngà နှစ်ထောင့် ကိုးရာ ငါးဆယ့် ငါး 2955
tăt’aun hnăya thoùn-zeh lè တစ်ထောင့် နှစ်ရာ့ သုံးဆယ့် လေး 1234
Notice that the syllable t’aun “thousand” may be changed to t’aún (low tone changed to creaky) when followed by another number. You may hear either c’auq-t’aun ngà-ya or c’auq-t’aún ngà -ya. The same tone change occurs with s’eh “ten” and ya “a hundred” (Lessons 1.6, 1.8).
Numbers beginning with one thousand often lose the first syllable. In place of tăt’aún tăya (1100), tăt’aún hnăyá ngà -zeh (1250) etc, you will hear t’aún tăya, t’au´n hnăyá ngà -zeh, etc. There is a similar variation for numbers beginning with tăs’eh (Lesson 1.6).
Variant.
In place of c’auq-t’aun ngà -ya etc you may sometimes hear c’auqt’aun- néh ngà -ya, literally “six thousand and five hundred”. More examples:
hnăt’aun kò-ya ngà-zeh ngà နှစ်ထောင့် ကိုးရာ ငါးဆယ့် ငါး 2955
hnăt’aun néh kò-ya ngà-zeh ngà နှစ်ထောင်နဲ့ ကိုးရာ ငါးဆယ့် ငါး 2955
tăt’aun hnăya thoùn-zeh lè တစ်ထောင့် နှစ်ရာ့ သုံးဆယ့် လေး 1234
tăt’aun-nék hnăya thoùn-zèh lè တစ်ထောင်နဲ့ နှစ်ရာ့ သုံးဆယ့် လေး 1234
There are similar variants for numbers in tens and units and in hundreds and units (Lessons 1.6 and 1.8).
