A child acquiring a language must learn to correctly match the phenomena of the realworld which he perceives with the lexical items and the segregates and perhaps some of the grammatical categories of the language to be learned. He must correlatively learn the organization in meaning of and among these last named elements, that is, the internal semantic map of the language to be learned. The developmental stages he goes through and the kinds of mistakes he makes on the way toward approximating the adult matching and map must increasingly become a target study of language acquisition investigation. Study of adult language must first be undertaken in order to properly trace the course of child speech development; accordingly the first section of the present paper follows an initial probing into the notion of matching and mapping. The second section theorizes that certain semantically-contentful aspects of the realworld have a universal representation in language in general and hence have an identical abstract encoding at the base of each language; these aspects participate in universal analytic semantic-structure; and these structures together embody a unified and integrated pattern perhaps ultimately with simple principles of organization. (The analysis in this paper is based on 70 pages of utterances of two Samoan children and an adult.) (Author/AMM)
