This study, contrasting grammatical structures in English and Hungarian, considers those areas of grammar in the two languages which would cause the greatest interference for the native English speaker learning Hungarian. The choice of topics is based on the author's personal observation, both of English speakers learning Hungarian and of Hungarian native speakers speaking English, and on a study of grammars of various kinds. The first part considers the article in general, and, in particular, the definite, indefinite, and zero article. Part 2 considers the category of definiteness, the definite article as a marker of definiteness, anaphoric and non-anaphoric definite personal pronouns, reflexive and demonstrative pronouns, the -ik pronouns and their English equivalents, indefinite pronouns, proper nouns, possessive constructions, and noun clauses. The third part involves morpho-syntax and considers such topics as sentence word order, interrogative and negative sentences, and phrasal verbs. Part 4 covers grammatical-semantic notions: time and tense usage, aspect, the category of number, and semantic considerations of number. References are listed. (VM)
