Significance of study
Vocabulary learning is important because of some reasons: First, the more vocabulary knowledge learners have, the better they can comprehend their reading assignment.
Second, learners who have more vocabulary knowledge can achieve more academic success because words are tools,
not only of better reading, but also of better writing, speaking, listening, and thinking as well.
Third, knowing enough vocabulary can guarantee success in life as well as academic areas (Nation, 2001).
There are a lot of ways to improve our knowledge of vocabulary and one of these ways can be having knowledge of affixes and roots which can help learners in learning unfamiliar words.
