Characters in this word

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

套 is made from 大 (large) and 長 (long), originally for something long, with some reference to hair; it later came to mean a cover or a linked group.

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