## AI Etymology
additionary comes from addition + -ary, from Latin additio ('an adding'), from addere ('to add'), from ad- ('to') + dare ('to give'). Morphologically, the word is transparent: -ary 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 adjective sense is "of the nature of an addition; supplementary", 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 addition, additional, add, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Latin additio, Latin addere, which anchor the explanation in named linguistic material.
