Ziwa is a word in the Aramaic language that means "basket." Aramaic is a very old language that was spoken in parts of the Middle East a long time ago. Ziwa is the word that people who spoke Aramaic would use when they wanted to talk about a container made of woven materials that they could use to carry things from one place to another.
Just like when you go shopping with your parents and they sometimes use a basket to carry things in the store, people a long time ago would use a ziwa to carry things too. A ziwa could be made out of all kinds of materials like sticks, grass, or even leather. People would put things like fruits, vegetables, or even tools inside the ziwa and carry it around with them.
So, in summary, Ziwa is the Aramaic word for a container-like basket that people used a long time ago to carry things around with them.
