What does the term "red words" refer to in reading instruction?

The term "red words" in reading instruction refers to words with irregular spelling. These words often do not follow standard phonetic patterns, making them challenging for students to decode using typical reading strategies. Teaching these words, which might include terms like "said" or "their," is crucial for developing reading fluency, as students need to recognize them quickly and without having to sound each letter out.

In contrast to the other options, which focus on different aspects of language and vocabulary, the concept of "red words" specifically highlights the importance of recognizing and memorizing these irregularly spelled words in order to enhance reading skills. Words that are commonly used in scientific contexts, frequently appearing in print, or difficult to pronounce may vary in their relevance and educational significance compared to the specific challenges posed by words with irregular spellings.
