It is purely subjective and one mans branch can be another mans twig☺.
Although a reasonable classification can be found in describing material for a fire.
One only uses twigs to start the fire but you then use branches to sustain it.

It is often helpful to identify if ones thoughts are subjective or objective.
If subjective it is perhaps best not to argue upon its virtue ...if objective find a link and let your opponent look it up and realise that you are right.
One could consider the difference between a stone and a rock...I think its a stone if you can use it in a shepards sling to kill a giant...a rock is something big enough to put at the head of his grave.

Well, contractually , when excavating, the difference between rock and a stone is that rock needs to be excavated with a particular technique and a anything other than rock, ie a stone or smaller, is less than 1/2 cum. and so can be carried away after being dug out.
I suppose that holds true with tree work. You can leave the twigs on the ground but the branches need to be removed ( or mulched) or the work would be unfinished. Not that all tree workers seem to get that idea.
That was not my objective and the post was not put up with that in mind but merely to demonstrate that a goggle usually shows something exists even though you dont think that it does.
