P.A.R. or PAR means Planed All Round when used in reference to timber. In other words, the timber has been prepared. The alternative is rough or sawn or unprepared timber. This has been cut to size but not finished in any way. Timber that is PAR is planed but there is no guarantee that the corners will be square!
Rough sawn timber is literally 'rough' and still needs to be dressed and planed to smoothness when bought. Rough sawn timber is popular because it's generally less expensive than other timbers.Rough sawn timber is produced at any saw mill, but instead of being planed, finished etc. the wood is left as it is.
Timber is just another name for wood, In practice wood in its rough form is usually refered to as timber, tree trunks unprocessed are probably timber in it's purest form. In a house unfinished wood ( generally found in the roof and beneath the floor) is referred to as timber e.g. roof timbers or floor timbers/joists. Timber which has been planed (smoothed) and finished off e.g. skirting boards and window sills are referred to as 'joinery' grade or finished, they are still however timber and the difference is a discriptive reference rather than a physical difference.

Timber comes in several stock forms, including rough sawn, which is freshly cut and has a rough surface; dressed or planed, which is smooth and uniform; and dimensional lumber, which is standardized in size for construction purposes. Additionally, timber can be processed into engineered wood products like plywood, oriented strand board (OSB), and laminated veneer lumber (LVL). These forms cater to various construction and woodworking needs.
Rough woods typically refer to types of timber that have not been planed or sanded, retaining their natural surface texture. Examples include oak, hickory, and pine, which can have a coarse grain and uneven surface. These woods are often used for rustic furniture, flooring, and construction. The rough surface can enhance the aesthetic appeal and provide better grip in certain applications.
