Origin

Compound word
构词法gòucífǎ
偏正piānzhèngModifier + head

The first part narrows down the second: it says what kind of thing the head is.

The word joins 前, 'before', and 天, 'day', for the day before today.

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

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