This research aimed to investigate and compare various vocabulary acquisition strategies used in foreign language learning and evaluate their effectiveness in terms of vocabulary development, retention, and overall language proficiency. A convenient sampling method was employed to select 100 students, with 10 teachers participating in the study. Data were collected through questionnaires comprising five different questions, along with pre and post-tests to assess the impact of the vocabulary acquisition strategies. The students were instructed using ten different strategies, and the findings revealed that the Contextual Clues strategy proved to be highly effective, yielding the highest average score among the strategies. Consequently, the research concludes that implementing the Contextual Clues strategy can be recommended as an effective approach for teaching vocabulary to foreign language learners, yielding optimal results.
