两百五十万 (liǎng bǎi wǔ shí wàn) — 2.5 million (two hundred fifty ten-thousands)

Two or more meaningful parts placed together so that their meanings combine into a new one.

This origin belongs to the traditional form 兩; 两 is its simplified writing.

The traditional form 兩 is described as combining 一 and 㒳. The simplified 两 is a later abbreviation.

Most characters — around four in five — are built this way: one part hints at the meaning, the other at the pronunciation.

百 combines 一, which carries the number meaning, with 白, which provides the sound.

A drawing of the thing itself, worn down over three thousand years into a few strokes.

An older form had a crossed mark between a top bar and a bottom bar. The modern 五 keeps those bars, while the original idea is uncertain.

An abstract idea shown by a mark or a diagram rather than by a picture of an object.

The early shape 十 was mostly a single vertical stroke, sometimes with a dot, and later gained a horizontal stroke to form a cross. For the number ten, it marked the next digit above one.

A drawing of the thing itself, worn down over three thousand years into a few strokes.

This origin belongs to the traditional form 萬; 万 is its simplified writing.

For 万, the form 萬 was originally a picture of a scorpion, later borrowed for its sound to write 'ten thousand'; the scorpion picture is unrelated to that number.
