beggary comes from beggar + the noun suffix -y. Beggar is from Middle English beggere, from beg + -ar, the verb beg being of uncertain origin. Morphologically, the word is transparent: -y and -ar is attached to the older base named in the history, so the modern form packages an inherited or borrowed stem inside a later English derivative. In modern use, the noun sense is "the state of extreme poverty or destitution", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as beggar, beg, beggarly, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Old French begart, Old French -erie, which anchor the explanation in named linguistic material.
