Free time

This is the vocabulary of invitations and weekends — the English people actually use when they are not at work.

hang out — to spend time relaxing with friends.

"What are you doing Saturday night? Do you want to come over and hang out?"

chill out — to relax and calm down.

"Don't worry about them, let's just chill out and forget about it."

drop in — to visit briefly, often without an invitation. Very close to pop in from the shopping lesson.

"You know them, they love to just drop in unexpectedly."

catch up (on) — to exchange the latest news, or to do something you have fallen behind on.

"I'm so tired. Can we catch up this weekend? I'll tell you crazy news."

work out — two meanings, and they have nothing to do with each other. One: to exercise. Two: to end well, or to find a solution.

"I work out at the gym three times a week." "Don't worry, everything will work out fine."

take up — to start a new hobby or activity.

"She took up painting last year and loves it." "I want to take up a new sport in my free time."

be into — to be very interested in or enthusiastic about something.

"He's really into photography these days." "Are you into video games?"

Where the object goes. take up splits: take it up. catch up on and be into never split: catch up on it, be into it. The rest — hang out, chill out, drop in, and work out in the exercise sense — usually take no direct object.
