The main goal of the paper is to show the value of texts preserved in more than one version for studies aimed at identifying reasons for the demise of words. The data selected is a set of six non-surviving English preterite-present verbs. The analysis of the material shows that mediaeval manuscripts often exhibit orthographic and morphological variation as well as differ in lexemes. Such differences prove to be useful for the search of factors leading to the elimination of the verbs in question.
Notes about a handbook of Italian grammar by a Croatian philologist Dragutin Antun Parčić – A handbook of Italian grammar, written in Croatian by Croatian philologist Parčić, confirms that in the past educated Croatian-speaking people were bilingual and at the same time it proves that lower classes aimed to study Italian as well. The paper analyses the functionality and appropriateness of topics presented in the Parčić manuscript because it is obvious that the author was keen to help his Croatian-speaking students in the acquisition of Italian.
