## AI Etymology
ingrateful comes from Latin ingratus ('unpleasant, unthankful'), from in- ('not') + gratus ('pleasing, thankful'), with the English suffix -ful added. An archaic variant of ungrateful. Morphologically, the ending is part of the etymology: the suffix is attached to the older base named in the history, producing a later English derivative. In present English, the adjective sense is "unthankful; failing to show gratitude (archaic for ungrateful)", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as grateful, ingratitude, and gratitude, and in derivatives such as ingratefully and ingratefulness. Its semantic neighborhood includes ungrateful, unthankful, thankless, and unappreciative, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Latin in- and Latin gratus.
