Phrasal verbs are an essential, though difficult to teach and learn, part of the English language. Although phrasal verbs are commonly used by native speakers, for English learners they pose a considerable challenge as far as their acquisition and use are concerned. The aim of this study is to examine students’ attitude towards phrasal verbs taught at the B2 level in upper-secondary schools, and to analyse the significance of these multi-word verbs. The paper presents an excerpt of a survey conducted among secondary school students, which examined their understanding of phrasal verbs and analysed students’ opinions about the importance of acquiring these demanding multi-word verbs.
