In Arabic, numbers from 1-10 are waaHid, ithnayn, thalaatha, arba:a, khamsa, sitta, sab:a, thamaaniya, tis:a, and :ashara. No monosyllabic numbers, and 8 has four syllables. And even these are short compared to the numbers in Inuktitut.
BTW, it's similar to German in that regard, because it's two-twenty.
Also interestingly, the way 8 sounds in Algerian Arabic would be 2 syllables. Although take it with a grain of salt because it's third-hand information. I learned this from my father, who's not native (but has lived in Algeria in his childhood)
What is the "one" night in that title? Any chance wa is related to waaHid?
No, wa (usually in basic sentences) means 'and'. Layla alone means one night. Alf is a thousand, and for certain numbers the singular is used over the plural, which is why it may seem confusing.
