Side Effect
= the secondary, usually unwanted effect from taking medicine or receiving medical surgery
Ex: The “side effect” from taking the medicine may include diarrhea or vomiting.
“Side effect” can also be used to describe other things with unintended consequences.
Ex: Using chemicals to kill insects may have many dangerous “side effects” for humans.
*Although it’s mostly used to show negative unintended consequences, “side effect” can sometimes describe positive unintended consequences.
Ex: One positive “side effect” of learning a new language is learning new words to express your feelings.
