Semantics is the study of linguistic meaning and the relationships between words, phrases, and symbols that contribute to human communication and expression. A study observed how children learn the meanings of words in their native languages. It was determined that children can deduce the meanings of unknown words when they know the overall meaning of the sentence in which the unknown words are spoken. This allows the children to “acquire partial knowledge from ambiguous situations and combine such partial knowledge across situations,” until a complete understanding is achieved.
