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!

Sawn timber is advantageous when a more rustic appearance is desired, as it retains the natural texture and character of the wood. It is often more cost-effective than planed timber and can be used in structural applications where precise dimensions are not critical. Additionally, sawn timber offers better grip for certain applications, such as in construction or outdoor projects, where slip resistance is important.
Oh, dude, rough sawn timber is basically wood that's been cut straight from the log using a saw, but it's not been planed or smoothed out all nice and pretty like your grandma's dining table. It's like the lumberjack of the wood world - all rugged and raw, ready to be transformed into something cool... or just left looking like a rustic charm in your backyard.

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.
