This article discusses the applicability of semantic field analysis to the study of development and change in important interpersonal relations on the example of parent-child relationships. The narrative material was compiled from responses of 348 teenagers and young adults aged 13-30 years. Participants wrote about their parents ('Tell me about your parents'). On the basis of the context, semantic fields were generated for the high-incidence phrase 'to love one's parents', which is the primary model of conceptualizing the parent-child relationship in our culture. The results demonstrate the material complexity of the 'love for parents' semantic field in the study group, and reveal the associative network of other semantic relations involving this concept. They also confirm the hypotheses on subtle developmental changes in the understanding of 'love for parents' between early adolescence and adulthood. The study presents the application of methods based on linguistic analysis of language to the analysis of developmental changes in important personal relationships.
