Tamaiti
Not independently attested as a distinct spirit of Tongan folklore. The word tamaiti simply means 'child' in Tongan, with cognates across Polynesian languages; no source documents a child-ghost named 'Tamaiti' haunting playgrounds and village commons. The entry is a generic children's-spirit archetype rather than a recorded Tongan figure, and no Tongan child-ghost tradition bears this name.
