How do you join wood without screws?

Wood can be joined without screws using several methods, such as wood glue, dowels, or biscuits. Wood glue creates a strong bond when applied to the surfaces being joined. Dowel joints involve drilling holes in both pieces of wood and inserting wooden dowels, while biscuit joints use oval-shaped pieces of wood (biscuits) to align and strengthen the connection. Other techniques include using mortise and tenon joints or finger joints for added strength and aesthetics.
