Children in early telegraphic stage demonstrate syntactic development by combining content words, and often omitting function words. This study tracked the first language acquisition descriptions of a three-year old child speaking the Waray-Waray language in the Philippines. Naturalistic home observations, interactions with the participant and unstructured in-depth interviews with the people surrounding the participant were used to collect the data for this study. In the first section of the results, it offers explanations of the developmental data of first language (L1) acquisition pertaining to a range of syntactic construction, including utterance representations, word order and production of word classes. The next section of the findings considers the various theories to explain the facets of development on the participants first language acquisition, including nurture determinants and the behaviourism perspective. The results support the claim that the process of language acquisition depends on the input that learners receive. Moreover, the findings also show and support the claim that a child following the telegraphic stage is able to produce multi-word utterances in which it is considerable that the childs word order is not the same as the adult-grammar, but relatively consistent and understandable.
