Abstract
Semantics is a study of literal meaning. There are many ways that are used to analyse the sentences based on semantics. One of them is thematic roles. Thematic roles is one of semantic interpretation which focuses on determining the roles of noun phrases in the sentences. This research analyses the thematic roles found in the conversations of one of Webtoon stories entitled Orange Marmalade based on thematic roles theory of O’Grady, Kearns, and Saeed. Moreover, this research analyses the equivalence of the data in which English becomes source language and Indonesian as translated script based on equivalent theory of Catford. This resarch is descriptive qualitative research. The findings of this research are (1) there are fifteen thematic roles played by the entity, and there are forty one rules of thematic roles whereas noun phrases as a subject explained by roles agent, experiencer, and author appear the most in the conversations based on topicalization. (2) The data consist of equivalent and non equivalent data. Equivalent data is devided into absolute equivalent 55%, equivalence with the shift of roles 38%, and equivalence translated into non simple declarative sentence 4%. While non equivalent data is devided into non equivalence with the shift of roles 2% and non equivalence translated into non simple declarative sentences 1%.
