Which of the following is a key component of vocabulary development?

Associating printed words with their meanings is a fundamental aspect of vocabulary development. This process allows learners to not only recognize words visually but also to comprehend them contextually. When students link words to their meanings, they enhance their ability to communicate effectively and understand written texts. This connection is crucial for building a robust vocabulary, as it goes beyond rote memorization and fosters a deeper understanding of language use.

In contrast, while understanding grammar rules is important for overall language proficiency, it does not directly contribute to the acquisition of vocabulary itself. Practicing spelling can help reinforce word recognition and writing skills, but it does not necessarily enhance the understanding of a word's meaning. Reading rapidly may improve fluency, but it can detract from the careful consideration of vocabulary and comprehension if it leads to skimming rather than deep engagement with the text. Thus, associating printed words with their meanings is the core element that directly supports vocabulary growth.
