Interesting ways people speak..... please do not take offense at the following, it is not intended to do so.....
Americans use the small number first when describing timber sizes (and there's more to that)
New Zealanders, Brits and I assume Aussies all start with the larger number.
Example - USA (and presumably Canucks) say 2" x 4" whereas we say 4" x 2" (or more colloquially 4-ba-2)
We called framing timber and the like "Timber" whereas 'Murican's call it "Lumber"
To me "lumber" is your lower back area that usually gives out after a certain age.
Another one is American's call concrete "cement" for some odd reason. Cement is actually an ingredient used to make up concrete, along with water and gravel/mix.
"Siding" is another one - we call it "Exterior wall cladding" or just cladding.
I hear a lot of American's say 'set' when they actually mean 'sit' - example - "I have an engine setting in the shop" (Wrong - you have an engine sitting in the shop).
You might have a bowl of custard 'setting' in the fridge, and also sitting on the shelf.
But the one that really gets up my nose is the frequent incorrect usage of the word 'then' when in actual fact the word 'than' should be used.
carry on as you were....
