A lumber room is a special room where people sometimes keep different things. It's usually a small room with lots of shelves and cabinets where you can store items that are not used often, but are still worth keeping.
Let's say you have a lot of books, toys, and other things that you don't use every day, but you don't want to throw them away either. You can put them in the lumber room to keep them safe and organized.
The lumber room can also be used for storing other things like clothes, blankets, seasonal decorations, or even tools. It's like a secret storage space where you can keep things out of sight but still have access to them when you need them.
In some older houses, a lumber room was also used to store wood for heating or cooking. People used to keep chopped wood logs in the lumber room so they were always available for use.
In summary, a lumber room is a special room used for storing things that are not regularly used but still worth keeping. It's like a private storage space where you can keep things organized and out of sight.
