Level 11 books provide more literary language, more complex sentence structures and less support from illustrations. Characters are more varied, with action sustained over several pages. Non-fiction titles include glossaries where necessary. Sentences are still short for better understanding. However, grammatical vowel endings are more evident to encourage fluent reading and to provide familiarity with some higher-level features of written Arabic.
