It is well known and acceptable in the language sciences that, in terms of language learning, knowledge is not exclusively those that directly reflect the language or culture of the bearers of that language. Academic, scientific or technical knowledge, empirical knowledge in a professional field is also important for receiving and understanding information in Romanian. Although the volume of linguistic knowledge and skills varies from one person to another and is dependent on the traits of a culture, they tend towards universality through general human values and this can greatly help the Gagauz student who acquires a lexical system of professional orientation and the one who teaches this lexical system. Once he has reached a certain level of lexicon knowledge through interactive teaching strategies, he has to demonstrate an appropriate linguistic behavior that demonstrates confidence in his or her knowledge.
