To interweave means to twist or blend things together so they become connected and hard to separate. Picture weaving a basket: you take individual strips and pass them over and under each other until they form a strong, unified whole. That's interweaving.

Writers interweave multiple storylines in a novel, switching between different characters whose stories eventually connect. A teacher might interweave history lessons with literature, showing how the books students read reflect the times they were written in. When you write an essay that connects ideas from science class with observations from your own life, you're interweaving different kinds of knowledge.

Things that are interwoven are linked together, supporting each other. In music, a composer might interweave melodies so they play simultaneously and harmonize. In your own friendships, shared experiences and memories become interwoven over time, creating bonds that strengthen the relationship.

You can also use interweave for physical things: vines interweaving through a fence, or threads interwoven in fabric.
