The rule, as people use it
Interjections are the small sounds people make when they react: oh, wow, oops, ouch, hmm, ugh, yay. They don't follow grammar rules, and that's the point. They show the listener how you feel before you say anything else, so a conversation feels alive instead of flat.
Each one has a job. "Wow" is surprise, good or bad. "Oops" is a small mistake, like dropping a spoon. "Ouch" is pain, or sympathy when a friend tells you bad news. "Hmm" means you're thinking. "Ugh" is annoyance. "Yay" is happy news, and people say it more to friends and kids than at work. "Uh-oh" means you just saw a problem coming.
Most learners don't make grammar mistakes here. They make silence mistakes. Someone tells you their flight got canceled and you say "OK". That can sound cold. "Oh no" first, then your answer, sounds like you're listening. Put the interjection at the start, add a comma pause, then keep talking.
One more to know: "oh" changes meaning with your voice. A rising "oh?" asks for more. A falling "oh" means you understand now. A long "ohhh" means you finally get it.

Read these five pieces of news and write your first reaction to each, starting with an interjection, then one more sentence: your friend got a new job; your coworker spilled tea on your laptop; the store is out of your favorite bread; you stepped on a toy; a friend asks where to eat tonight. Say all five out loud with feeling in your voice, the way you'd say them to a friend.
Say it today
Use it once in a real conversation before tomorrow. Out loud counts, even to yourself.
