Etymology: "Aidful" is about as plain as English word-building gets: it is "aid" with the suffix "-ful" attached, and the suffix does most of the work. "Aid" came into English from Old French "aider," which descends from Latin "adiutare," meaning to help repeatedly or assist. The "-ful" ending, from the Old English "full," is a suffix meaning "full of" or "characterized by," so a helpful person or thing is one full of aid. The same pattern gives "hopeful," "thankful," and "careful." Because the word is formed transparently, its meaning follows directly from its parts: the adjective describes something that gives help or support in a given situation. It is a rare word, used mainly where a writer wants to describe someone or something actively supportive, and its structure makes it easy to understand even on first encounter.
