Which method is least beneficial for vocabulary improvement?

Mere rote memorization of words is the least beneficial method for vocabulary improvement because it focuses solely on memorizing definitions or lists without engaging with the words in a meaningful way. This approach often lacks context, which is crucial for understanding how words function in different situations.

Vocabulary acquisition is most effective when it's integrated with context, allowing learners to see how words are used in sentences, conversations, or writing. Other methods, such as regular reading, using words in context, and incorporating vocabulary into writing and speaking practice, encourage active learning and deeper comprehension. These methods help learners to not only remember the words but also to understand their nuances, proper usage, and the relationships between words. In contrast, rote memorization may lead to superficial knowledge that doesn't translate into practical language skills.
