[Zhongwen.com](http://zhongwen.com/cgi-bin/zipux.cgi?=%A4K) says that 八 is an "ideograph representing division", what is easy to see. So the old meaning of "separate" is also clear. But how did it came to represent the number 8?

All I've found so far is its association with 发 (发财), thus with good luck in general.

I want to know if there's any relation between "separate" and "8".

Generally speaking, we cannot create pictures or ideograms for every [morpheme](https://en.wikipedia.org/wiki/Morpheme) in a language; we'll quickly run into practicality issues if we try to do so. 「八」 ([Baxter-Sagart OC](https://en.wikipedia.org/wiki/Reconstructions_of_Old_Chinese#Baxter%E2%80%93Sagart_(2014)): **/\*pˤret/**) should be treated as just a [rebus](https://en.wikipedia.org/wiki/Rebus#Rebus_principle) or [phonetic loan](https://en.wikipedia.org/wiki/Chinese_character_classification#Rebus_(phonetic_loan)_characters) for *eight*.

As an ideogram representing *to separate*, 「八」 either [represented a morpheme [cognate](https://en.wikipedia.org/wiki/Cognate) with] or [was the original representation of] 「分」 (**/\*pə[n]/**, *to separate*), with the component 「八」 serving simultaneously as a meaning and sound hint in 「分」.

If 「八」 was the original form of 「分」, then in terms of character development, 「八」 complexified into 「分」 via the addition of 「刀」 (*knife*, indicating the meaning *to separate an object into two with a knife*) after 「八」 was overused for the meaning *eight*, causing a need to disambiguate the two morphemes *eight* and *separate*.

In any case, it is quite likely that the original morpheme that 「八」 represented is now [also] written as 「別」 (**/\*pret/**, *to divide*). The financial numeral for *eight*, 「捌」, still uses 「別」 as a phonetic component, showing the conservative nature of the sound of 「八」 for an ancient morpheme meaning *to divide, differentiate, separate*.

The *good luck and fortune* meaning (發財) is an unrelated wordplay, although it touches on the same kind of rebus principle. 「發」 ([Middle Chinese](https://en.wikipedia.org/wiki/Middle_Chinese): **/pʉɐt̚/**) sounds similar enough to 「八」 (**/pˠɛt̚/**) for this purpose, and in an alternate universe or a now-lost topolect, 「八」 might have been used as a phonetic loan for 「發」.
