sinister

An ominous or suspicious feeling can make someone think that something is sinister.

The word "sinister" often gets used when people talk about movies, books, and news. It usually means something seems scary, strange, or unfair, like a plot twist in a thriller novel. Imagine you're reading a story where the main character starts to suspect that their best friend is working against them – that's pretty sinister! In everyday life, someone might say "There's something sinister about this new policy" if they think it's going to hurt people unfairly. It can also be used in general conversations, like when you watch a movie and say "This plot is getting really sinister."
