Sight Words
Edward William Dolch and Edward Fry introduced lists of "sight words" or "instant words" that beginning readers should be taught to memorize as "whole words" rather than attempt to decode the letters as individual sounds using the grapheme-phoneme correspondences of phonics and the alphabetic principle.

These "high-frequency" words account for over 50 percent of all the words in typical speech and in popular print media like newspaper articles and novels. They account for over 75 percent of words in the primers and basal readers used teaching reading in elementary schools.

The first few hundred common words are almost all words that survive from the days of anglo-saxon "Old English," so are among the most irregularly spelled words.

Nevertheless, most of Dolch's list of 220 sight words and Fry's 1000 "instant words" actually can be decoded phonetically if the student is aware of the departures from one letter-one sound alphabetic principle, such as the "silent E" and the "vowel + R" rules.

Many teachers, especially those who developed their own phonics programs over the past two hundred years, taught these rules explicitly with drills including many examples.

But some of today's teachers, especially those trained in "whole-language," reject direct instruction of basic phonics skills.

It is quite likely that even pre-school-age children know the meanings and the unusual pronunciations of these most common words, so when read to by teachers and parents their brains will be trained to recognize the variant pronunciations of some vowels and consonants.

Most of these children will become rapid decoders and fluent readers without the need for extensive and boring drills.
