Other commentsː Oroha has a very regular, base ten counting system, as you can see. Tanahuru is almost exclusively used in counting, if you count to ten you use tanahuru (you can also say aawara, but it is rarer), if there are ten things, you say aawara, never tanahuru; if you are counting past ten, you will still only use tanahuru for ten, not for twenty *rua tanahuru. It might be better to translate aawara as 'a group of ten'.
The na in parentheses above means 'and' which can be used with 110, but seemingly not with any other number, or at least I have no data with a speaker saying, for example, *tanarau na rua aawara mana hiu (127); they would omit the na.
There is also mora which can mean "uncountable; a lot" which is most commonly used with mass nouns, though can be used for count nouns, or in more metaphorical senses.
for a particularly large number, they will commonly just mora, but if they wanted to be specific they could say, for example, 3,759,804 which would be ooru pera hiu tanahuru nima aawara mana siwa sinora waru tanahuru mana hai. Just like English this gets very long when written out.
For dates (specifically years) they almost always use phonemicised English, for example, nainutiini nainiti wani, "nineteen ninty one" (in casual speech a syncope/apocope rule applies, and it often sounds like naintiin nainti wan). They did not reckon dates before colonialism, so they used English as the default, even when speaking in fluent Oroha.
Oroha is a critically endangered Austronesian language (7 on the EGIDS scale) spoken fluently by fewer than one hundred people; it is one of the most endangered languages in the Solomon Islands. Four villages on Small Malaita host all the fluent speakers of Oroha, the majority of those speakers are middle-aged or older, there are semi-speakers of Oroha found in other cities such as Auki and Honiara.
