Counting in Indic languages

To commemorate my 100th post on this blog (yes, it's been a hundred) and the fact that I'm learning some Assamese here in Guwahati, I thought I'd talk about learning to count in an Indic language - basically any one of the many Indo-European languages spoken on the Indian subcontinent, including Hindi, Bengali, Nepali and Assamese.

Now I'm not talking about their numeral systems, since most of us use a derivation of the Hindu or Hindu-Arabic numeral system on a daily basis, which is a decimal system that uses only 10 digits from 0 to 9. What I'm talking about are the names for the numbers in these languages.

Now non-native speakers learning to count in English from 1 to 100, technically only need to memorise the names of the numbers from 1 to 20, then every multiple of 10 till 100. That's because after 20, we simply say 20 'twenty' and 1 'one' to get 21 'twenty one'; 20 'twenty' and 2 'two' to get 22 'twenty two' and so on. However, they still need to learn what 11-19 are since we don't say 'ten one' for 11, or 'ten two' for 12. They also need to learn the names for the multiples of 10 since these are not entirely regular - we don't say 'three-ty' for 30 or 'five-ty' for 50. (Sure, you might say there's a pattern with 40 and 60-90, but it's not as regular as say, 21-29.)

What non-native speakers find learning to count in Indic languages is that while there are some patterns like the kind you find from 60 'sixty' to 90 'ninety' in English, most of the time it seems like you just have to memorise the name of every single number from 1 to 100.

For instance, if we look at 5, 15, 25, 35 ... 85, 95 in Hindi:

5 पाँच paaNch (N indicates nasalisation on the preceding vowel)
15 पन्द्रह pandrah
25 पच्चीस pachchiis          (20 is बीस biis)
35 पैंतीस paiNtiis              (30 is तीस tiis)
45 पैंतालीस paiNtaaliis      (40 is चालीस chaaliis)
55 पचपन pachapan          (50 is पचास pachaas)
65 पैंसठ paiNsaTh             (60 is साठ saaTh)
75 पचहत्तर pachahattara     (70 is सत्तर sattara)
85 पचासी pachaasii            (80 is अस्सी assii)
95 पंचानबे paNchaanabe     (90 is नब्बे nabbe)

You can sort of see a pattern, but it's not quite possible to analyse each form morphologically and tease out the part that means 'five units'. Goodness also knows when to decide when to nasalise the vowel or not. Also, look at the words for 25 (pachchiis) and 50 (pachaas) - I always get their Nepali counterparts mixed up.

Assamese isn't much different. Here're the numbers from 1-12 in Assamese - which is as far as I'll go for now since it'll allow me to tell the time. I'll probably get up to 31 so I can give dates, and also learn a few more multiples of 10.

1 এক ek
2 দুই dui
3 তিনি tini
4 চাৰি sari
5 পাঁচ pans [pãs]
6 ছয় sôy [sɔj]
7 সাত xaat
8 আঠ aath
9 ন nô [nɔ]
10 দহ dôh
11 এঘাৰ egharô
12 বাৰ barô

When I come up with a good way to memorise the numbers from 0 to 100 in such languages I'll let you know. In the meantime, thank goodness people here in Guwahati also use English numbers.
