Plywood is a wood product that is produced by gluing some plies of hardwood or softwood together.
It is resistant to many common annoyances found in solid wood, such as shrinking, cracking and twisting. Plywood is also a strong and durable material and it is more environmentally conserving, due to the fact that plywood can be made into sheets that are much wider than the original trees.
Different types of plywood are used for a wide variety of different things, including dog kennels, flooring, furniture, fences, framing, barns, yachts, roofs, mailboxes and shelving.

Any strong wood. In the US, softwood plywood is generally made from Douglas fir or southern yellow pine. Most hardwood plywood is "veneer core." This means they make sheets of plywood from poplar--an inexpensive hardwood but plenty good for plywood--then put veneers of a more expensive hardwood on both sides of the finished sheet. If you run into oak "marine plywood" all the plies are made from oak. Oak is extremely hard to make into good plywood cores because it is so hard, so oak marine plywood is really expensive.
