Vocabulary is one of the strongest engines of language development, and it grows best in context, through repetition, and with plenty of reading. Rather than memorizing words in isolated lists, encountering them in reading, speaking, and real use is far more durable. Content tied to the child's interests both speeds up and enlivens vocabulary learning.
Detailed Explanation
Building vocabulary is one of the most valuable investments in language learning, because vocabulary is one of the strongest predictors of both speaking and reading comprehension. The good news: the effective ways to learn words are well established.
Words are best learned in context
As literacy resources like Reading Rockets emphasize, children learn most words not from isolated lists but indirectly through real experiences like reading and speaking. Studies on second-language reading also show vocabulary contributes strongly to comprehension (PLOS One). So seeing a word in context, several times and in different situations, is far more durable than memorizing it in a dry list.
Repetition and interest: two powerful multipliers
Two things make a big difference in vocabulary learning: spaced repetition (encountering a word several times over time) and interest (connecting to topics the child loves). When a child reads or watches English content on a topic they're interested in, they acquire new words without realizing it and with enjoyment. This is the most natural and sustainable way to learn vocabulary.
To expand vocabulary
- Provide plenty of reading; reading is the strongest source of vocabulary learning.
- Introduce new words in context; avoid isolated list memorization.
- Ensure re-encountering the same word at different times (spaced repetition).
- Choose content tied to the child's interests; interest speeds learning.
- Encourage using new words in speaking and writing; use consolidates.
Points to keep in mind
Memorizing long word lists without context may look "learned" short-term but usually isn't durable and tires the child. Also, turning word count into a target (so many words a day) can create pressure. The real goal is being able to actually use the word; that comes through context, repetition, and interest.
Expert Note — Andrea Massari Rosario
I don't make my students memorize words; I introduce them to words. When a child sees a word in a story, a game, and a conversation, that word becomes theirs. A memorized word is forgotten; a lived word stays. So the best vocabulary belongs to the child who reads the most and speaks the most.
