Furthermore, while phonetic clues are useful as one technique, it is usually not very efficient to sound out entire words. Phonetic clues work best when combined with other strategies. Also, remember that beginning readers should not be expected to sound out words such as names or concept words that are not already part of their spoken vocabulary. No single element works all the time for everyone. Successful readers use different combinations of strategies and word analysis skills.
Some approaches are easier for some readers than others.
That is why it is essential to help beginning readers learn to use all the approaches as they become ready to do so.
