In five phonic generalizations, this article introduces a logical system of letter-sound relationships. Ranging from 91% to 99% phonic transparency, these statements generalize a study of 16,928 words in children's literature. The r-controlled vowels aside, the analysis shows 54 basic transparent letters and letter combinations, 39 transparent phonograms, and 11 nontransparent phonic cells. The generalizations--written in basic, phonogram, and unfit clauses--begin with the following five basic clauses: (1) single vowels usually have their short sound; (2) final single vowel-consonant-e words usually have a long first vowel and a silent final "e" (-VCe); (3) vowel digraphs usually have one or one of two sounds; (4) single consonants usually have one or one of two sounds; and (5) consonant di/trigraphs usually have one or one of two sounds. In total, single letters, di/trigraphs, -VCe, phonograms, and unfit cells comprise a coherent phonic system. The article concludes with teaching suggestions. (Contains 5 tables.)
