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.

双 means double, and 星 means star, so the word refers to two stars close together.

Characters in this word

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

又又双

双 is made of two 又 parts side by side. Repeating 又 gives the sense of a pair.

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

The top of 星 is a later simplified form of 晶, twinkling stars; the bottom 生 shows the sound.
