To refurbish means to clean, repair, and improve something old or worn so it works well and looks good again. When a company refurbishes an old computer, they might replace broken parts, clean dust from inside, update the software, and polish the case until it looks almost new. When a theater refurbishes its building, workers might repair the seats, repaint the walls, fix the lighting, and restore decorative details.

The word suggests making something functional and attractive again without building it from scratch. It's more thorough than just cleaning: refurbishing means fixing what's broken, replacing what's worn out, and restoring the overall quality. A school might refurbish its library by repairing damaged shelves, replacing torn carpet, updating the furniture, and giving everything a fresh coat of paint.

People refurbish furniture, electronics, buildings, and even boats or cars. The goal is to bring something back to useful life rather than throwing it away. When you see a “refurbished” item for sale, it means someone has carefully repaired and restored it, often making it nearly as good as new but usually less expensive than buying something brand new.
