Words and concepts are inseperable components of language education. Examining words and concepts gives information about language development and education. Lexical development in mother tongue occurs by means of spoken and written texts children are exposed to. Types of these texts can be diversified. This study is aimed to categorize concepts in children’s stories and to reach principle findings about lexical hierarchy and education. It’s mainly based on indirect observation, content analysis, category analysis and frequency analysis so as to determine conceptual and sub-conceptual categories in children’s stories. Data of the study consist of 20 stories for 5;0+ year-old-children. Lexical data were analysed/categorised according to Clark (2003). Major findings of the study: There are nouns, verbs, adjectives, adverbs, pronouns, prepositions, set phrases, exclamations, echo-words and specific names in the stories. Specific names, idioms and proverbs are out of the limitations. In this way, there are 4606 words in database, 1629 of which are nouns, the most used category. There are totally 1306 verbs. So the category of verbs is the second most used category. Studies determining the concepts and vocabulary in written texts for children is important in terms of children's literature and corpus studies. It’s expected to contribute to literature.
