Shades of meaning
To add is to increase by adjoining or uniting: in distinction from multiply, which is to increase by repeating. To augment a thing is to increase it by any means, but this word is seldom used directly of material objects; we do not augment a house, a farm, a nation, etc. We may enlarge a house, a farm, or an empire, extend influence or dominion, augment riches, power or influence, attach or annex a building to one that it adjoins or papers to the document they refer to, annex a clause or a codicil, affix a seal or a signature, annex a territory, attach a condition to a promise. A speaker may amplify a discourse by a fuller treatment throughout than was originally planned, or he may append or subjoin certain remarks without change of what has gone before. We cast up or sum up an account, though add up and make up are now more usual expressions.
