To dissect something means to carefully cut it apart to examine its pieces and understand how it works. In science class, students might dissect a frog or flower, making precise cuts to see the organs, tissues, and structures hidden inside. Scientists and doctors dissect specimens to learn about biology and anatomy.

When you dissect something, you take it whole and methodically separate it into its components. A biology student dissecting a preserved frog learns where the heart sits, how the legs connect, and what the inside of a lung looks like.

The word also applies to careful analysis of ideas and creative works. When you dissect an argument, you break it down into its individual claims to see which parts make sense and which don't. A book club might dissect a novel's plot, examining each chapter to understand the author's choices. Your teacher might dissect a math problem on the board, showing each step so the class can follow the logic.

Whether you're dissecting a flower to see its pistil and stamens, or dissecting a poem to understand its metaphors, you're taking something complex and studying its parts to grasp the whole more deeply.
