Things that are added or joined to something else; the plural of addition.
From Old French 'addition' and Latin 'additio' (an adding), from 'addere' (to add to), formed from 'ad-' (to) and 'dare' (to give). The root idea is 'giving toward' or 'putting toward.'
Mathematically, addition is the foundation of how we quantify reality—ancient Babylonians had sophisticated addition systems 4,000 years ago! But the word itself comes from this gorgeous Latin metaphor of 'giving toward,' treating math as generosity.
