Language contacts can be studied in three directions: language acquisition; b) language borrowing; c) translation. In this project all the three directions are investigated. The process of language borrowing is analysed on four levels: phonological, morphological, semantic, and syntactic. The adaptation of a model (a foreign word) shows two kinds of changes, primary and secondary changes, which take place on all four levels. The adaptation on the quoted levels is carried out according to the three types of transphonemization (zero, compromise and free) and according to the degree of the change of meaning on the semantic level.
