The name for words like motel and brunch is portmanteau. They’re also called blended words , because they blend parts of two words into one new word.

Examples

  • motel = motor + hotel
  • brunch = breakfast + lunch

Quick note

A compound word is different: it usually joins whole words together, like “toothbrush,” while a portmanteau fuses parts of words.

TL;DR: motel and brunch are portmanteaus, also known as blended words.
