PRESENT PERFECT SIMPLE AND THE USE OF “FOR” AND “SINCE” IN ENGLISH GRAMMAR
Keywords:
Present Perfect Simple, for, since, English grammar, tense system, language acquisition, duration, communicative competence, grammar teaching, temporal expressions, ESL learning.Abstract
This thesis analyzes the grammatical structure, semantic characteristics, and communicative functions of the Present Perfect Simple tense in modern English, with special attention to the prepositions “for” and “since.” The study examines how these grammatical units express duration, continuity, and the relationship between past actions and present results. Scientific and methodological sources related to English grammar teaching were comparatively analyzed. The research also investigates common difficulties faced by English language learners in the use of Present Perfect constructions. The findings demonstrate that mastering the distinction between “for” and “since” significantly improves communicative competence and grammatical accuracy in English language acquisition. The article is based on factual linguistic data and modern grammatical theories. [1], [2]
