Learning and acquiring a second language (L2), as well as the first language (L1), does not only imply the four most important skills: reading, writing, speaking, and listening. An important role in acquiring any language belongs to the knowledge and understanding of “the language rules” - grammar. Many people see grammar as a problem, and for some personal reason, they do not like to learn it. It seems that grammar inspires fear and is the most difficult part of language learning, and that is why the primary goal in this research was to find out about students' attitudes concerning the acquisition of English grammar (English as a second language) and Croatian grammar (Croatian as a first language), regardless of their love of grammar. The research was conducted using a qualitative method with a questionnaire consisting of two open-ended questions, and it involved 80 future elementary school generalist teachers, who are also studying to be teachers of English. The participants were first-year and third-year university students. The main reason for choosing these two groups is that they have the same major, but at the same time, they have a different level of language acquisition, and different experience with teaching practice in classrooms. The analysis showed that students considered grammar important, with a smaller emphasis on the first language grammar. They see the second language grammar important for teaching others, but also for enabling easier communication and better fluency. As for the grammar of the first language, the students think there should not be much stress on it since the first language surrounds us on a daily basis and we adopt the grammar naturally. However, they still consider grammar important in order to understand the language better and to acquire new (foreign) languages easier. As far as students' attitudes based on their year of study are concerned, no significant differences were noticed.
