The present paper gives a brief overview of the research on dictionary use and presents the results of a survey completed by upper intermediate level ELF Students of Sapientia Hungarian University of Transylvania on the use of dictionaries. It also reflects on the vocabulary learning strategies upper-intermediate students tend to use, their difficulties in improving their vocabulary skills (known as the intermediate plateau), as well as on the factors that often hinder the acquisition of new vocabulary (e.g., the lack of certain skills, like noticing). Finally, taking into consideration the fact that students prefer the use of search engines and AI-powered tools, the paper encourages a vocabulary practice that includes the use of electronic dictionaries combined with linguistic databases and AI-powered tools, which can help students not only to become autonomous learners but also to develop their metalinguistic and collocational awareness.
