A scream is a very loud sound that people make when they are feeling extremely scared or upset. It's usually a sign that something is wrong and they need help.
When someone screams, it can be quite startling for others around them. Imagine you're walking in the park and suddenly hear a blood-curdling scream coming from behind a bush - it would definitely get your attention! That's what happens when someone lets out a really loud shout because they're in trouble or are trying to alert others to danger. People might scream if they see a wild animal, like a bear, approaching them, or if they're caught in a bad accident. Even kids might scream if they fall down and scrape their knee - it's just a natural response to pain or fear.
A loud, emphatic, exclamation of extreme emotion, especially horror, fear, excitement, or anger; it may comprise a word or a sustained, high-pitched vowel sound.
To cry out with a shrill voice; to utter a sudden, sharp outcry, or shrill, loud cry, as in fright or extreme pain; to shriek; to screech.
