ONE SHEEP ON FIFTEEN ON TWENTY
Or 36 sheep to you....
Welsh counting is mental
From Wiki:-
The traditional counting system used in the Welsh language is vigesimal, i.e. based on twenties where numbers from 11 to 14 are "1–4 on ten", 16–19 are "1–4 on fifteen" (though 18 is more commonly "two nines"); numbers from 21 to 39 are "1–19 on twenty", 40 is "two twenty", 60 is "three twenty", etc.
There is also a decimal counting system, where numbers are "x ten y" unit(s), e.g. thirty-five (35) in decimal is tri deg pump (three ten five) while in vigesimal it is pymtheg ar hugain (fifteen – itself "five-ten" – on twenty).
So:-
| Number | Vigesimal system | Decimal system |
|---|---|---|
| 0 | sero/dim | |
| 1 | un | |
| 2 | dau (m), dwy (f) | |
| 3 | tri (m), tair (f) | |
| 4 | pedwar (m), pedair (f) | |
| 5 | pum(p) | |
| 6 | chwe(ch) | |
| 7 | saith | |
| 8 | wyth | |
| 9 | naw | |
| 10 | deg/un deg, deng | |
| 11 | un ar ddeg ("one on ten") | un deg un |
| 12 | deuddeg, deuddeng | un deg dau/dwy |
| 13 | tri/tair ar ddeg | un deg tri/tair |
| 14 | pedwar/pedair ar ddeg | un deg pedwar/pedair |
| 15 | pymtheg, pymtheng | un deg pump |
| 16 | un ar bymtheg ("one on fifteen") | un deg chwech |
| 17 | dau/dwy ar bymtheg | un deg saith |
| 18 | deunaw/tri/tair ar bymtheg ("two nines"/"three on fifteen") | un deg wyth |
| 19 | pedwar/pedair ar bymtheg | un deg naw |
| 20 | ugain | dau ddeg |
| 21 | un ar hugain ("one on twenty") | dau ddeg un |
| 22 | dau/dwy ar hugain | dau ddeg dau/dwy |
| 23 | tri/tair ar hugain | dau ddeg tri/tair |
| 24 | pedwar/pedair ar hugain | dau ddeg pedwar/pedair |
| 25 | pump ar hugain | dau ddeg pump |
| etc. | ||
| 30 | deg ar hugain ("ten on twenty") | tri deg |
| 31 | un ar ddeg ar hugain | tri deg un |
| 32 | deuddeg ar hugain | tri deg dau/dwy |
| 40 | deugain ("two twenty") | pedwar deg |
| 41 | deugain ac un ("two twenty and one") | pedwar deg un |
| 50 | hannercant/deg a deugain ("half a hundred"/"ten and forty") | pum deg |
| 51 | un ar ddeg a deugain | pum deg un hanner cant ac un |
| 60 | trigain ("three twenty") | chwe deg |
| 61 | trigain ac un | chwe deg un |
| 70 | deg a thrigain ("ten and three twenty") | saith deg |
| 71 | un ar ddeg a thrigain ("one on ten and three twenty") | saith deg un |
| 80 | pedwar ugain ("four twenty") | wyth deg |
| 81 | pedwar ugain ac un | wyth deg un |
| 90 | deg a phedwar ugain ("ten and four twenty") | naw deg |
| 91 | un ar ddeg a phedwar ugain ("one on ten and four twenty") | naw deg un |
| 100 | can(t) | |
| 200 | dau gant | |
| 300 | tri chant | |
| 400 | pedwar cant | |
| 500 | pum cant | |
| 600 | chwe chant | |
| 700 | saith cant | |
Then just to make it a little harder....
There are, for example, masculine and feminine forms of the numbers "two" (dau and dwy), "three" (tri and tair) and "four" (pedwar and pedair), which must agree with the grammatical gender of the objects being counted. The numerals for "five", "six" and "hundred" (pump, chwech and cant) also have reduced forms (pum, chwe, can) when they precede the object they are counting. The words for "ten", "twelve", and "fifteen" (deg, un deg dau/deuddeg, un deg pump/pymtheg) have the alternative forms deng, deuddeng, pymtheng used before nasals (which may be the result of mutation) and, occasionally, vowels;
back in 2009 I explained how to count like a basque miller
Seems they liked 20's too
