Which stage is described by decoding unknown words using chunks and known spelling patterns, rather than letter-by-letter?

• A. Pre-alphabetic
• B. Partial alphabetic
• C. Consolidated alphabetic
• D. Full alphabetic

Answer: (C)

Decoding by using chunks and known spelling patterns means the reader is recognizing familiar letter groups and patterns (like digraphs such as sh, th, ch, or common endings like -tion, -ing) to read unfamiliar words, instead of sounding out each individual letter one by one. This ability to group letters into meaningful units and apply pattern knowledge shows the reader has moved beyond simple letter-by-letter decoding and is using orthographic knowledge to unlock words more efficiently.

This describes the consolidated alphabetic stage. At this point, readers rely on these chunks and patterns to decode new words and read multisyllabic words more easily. They can also handle more complex spellings and larger word units by recognizing common phonograms and syllable patterns.

Other stages involve different approaches: the pre-alphabetic stage relies on non-letter cues or whole-word guessing, the partial alphabetic stage uses some letter-sound connections but still often decodes via partial or incomplete mappings, and the full alphabetic stage focuses on applying complete letter-sound correspondences and blending each sound more explicitly. The emphasis on using chunks and patterns specifically points to the consolidated alphabetic stage.
