A thematic or lexical-set approach organizes vocabulary around topics such as education, environment, or technology. Research shows that grouping related words enhances memory and facilitates contextual learning (31Memorize, 2024). When vocabulary is presented in meaningful clusters, learners create associations that make recall easier. For example, in an IELTS discussion about climate change, using a cohesive set pollution, renewable energy, sustainability, emission, conservation shows both fluency and lexical control.

According to 31Memorize (2024), creating thematic lists begins by selecting an engaging topic, gathering relevant words from reading or real-life materials, organizing them into categories, and including example sentences. Each item should include definition, part of speech, and collocation to strengthen understanding. The article also promotes spaced repetition, a learning technique where vocabulary is reviewed at increasing intervals (e.g., one day, three days, a week, two weeks) to transfer it from short-term to long-term memory. Spaced study reinforces retention and helps learners maintain a balanced study routine.

The British Council’s TeachingEnglish platform defines a lexical set as “a group of words related by topic, form, or function” (British Council, n.d.). Teachers are encouraged to use interactive activities such as sorting words into groups, chaining games (“I went to the market and bought…”), and “odd one out” exercises to build familiarity. These methods allow learners to see how vocabulary connects within real communicative contexts. Visual posters and thematic projects further aid retention and engagement.

For IELTS preparation, lexical sets provide a strategic advantage. The exam evaluates the range and appropriacy of vocabulary, so mastering words by topic allows candidates to speak and write more naturally about familiar subjects. For example, a student who has prepared thematic sets for education and health can quickly recall collocations like access to education, curriculum development, public health, and medical research.

When thematic study is combined with spaced repetition, learners experience continuous improvement without overload. Digital tools such as Anki, Quizlet, or 31Memorize can automate review intervals and track progress. This structured approach transforms passive memorization into active recall practice, promoting deeper mastery of lexical resources essential for both academic and everyday communication.
