Fig. 5: Orthographic detectability of the 25 most common suffixes in the CYP-LEX corpus across all age bands.
From: Morphology in children’s books, and what it means for learning

Each suffix is represented by a black vertical bar, with its height indicating the number of distinct words identified as containing that suffix based on their spelling. The colours denote the detectability status of the words: green represents genuinely complex words detected by the RegEx algorithm, grey represents genuinely complex words not detected by the algorithm, and blue represents pseudo-prefixed words.
