Vocab: lõõgastuma - to relax

to relax; to unwind; to loosen up; to become calm and free of tension; (about a person:) to rest and let go of stress

Building blocks

• lõõgast- → from lõtv (slack, loose)—the idea of tension being released

• -u- → reflexive suffix: “to become / to do to oneself”

• -ma → infinitive ending

So literally lõõgastuma means: “to make oneself slack” → to let the tension go.

How to use it

What to remember

• Because it's intransitive, it doesn't take a partitive object. Instead you add where or how you relax — and the place is usually in the Inessive case (ending -s).
