absorption

Soaking something up

Absorption is the process of taking something in.

A sponge absorbs water; the body absorbs nutrients; a company absorbs a smaller rival.

Mental absorption means being fully engaged: She was so absorbed in her book she didn't hear the doorbell.

In physics, absorption refers to energy being taken up rather than reflected or transmitted.

The word often implies that what's absorbed becomes part of something larger and loses its separate identity.
