This study provides an in-depth contrastive analysis of monolingual and multilingual user manuals from the perspectives of linguistics, culture, and translation studies. The user manuals are sourced from companies that are represented in both national and international markets. The Turkish and German originals are examined within their respective cultural contexts for linguistic, cultural, and translational characteristics, with the insights gained serving as a valuable contribution to successful intercultural communication. The focus is on the complex text and sentence features and their function as culture-specific identifiers in the German and Turkish user manuals.
