There are minor differences between the First and Second Editions of Uncovering the Logic of English. This page provides details on these changes and other minor updates included in more recent printings.

Edition History: Uncovering the Logic of English

Second Edition (Current Edition) published in 2012 as Uncovering the Logic of English: A Common-Sense Approach to Reading, Spelling, and Literacy. 208 pages. ISBN: 978-1-936706-21-1

• New content: Appendix J, "American, British, Canadian, and Australian Spellings."
• Minor content updates, including adding a fourth sound of the phonogram i: /ē/, as in piano or stadium.

We have also made several minor corrections to the 2nd Edition throughout subsequent printings, as well as the following content updates:

• Added the phonogram es, plural noun, and third-person singular verb suffix, which says /ĕz-z/.
• Phonogram ou: added a fifth sound, /ü/ as in could.
• Phonogram x: We added the second sound, /z/, as in xylophone. Previously taught as an advanced phonogram; however, some teachers like to introduce it earlier because of the prevalence of the word xylophone in children's alphabet books.
• Spelling Rule 7 expanded, clarified, and split into two parts:
  • 7.1 - Y says /ē/ only in an unstressed syllable at the end of a multi-syllable word.
  • 7.2 - I may say /ē/ with a silent final E, at the end of a syllable, and at the end of foreign words.
• Spelling Rule 10 expanded: "...A may also say /ä/ after a W or before an L."
• Added Spelling Rule 31: 
  
  • 31.1 Any vowel may say one of the schwa sounds, /ŭ/ or /ĭ/, in an unstressed syllable or unstressed word.
  • 31.2 O may say /ŭ/ in a stressed syllable next to W, TH, M, N, or V.
  • 31.3 AR and OR may say their schwa sound, /er/, in an unstressed syllable.
• Spelling rules wording clarifications:
  • Rule 1 - "C always softens to /s/..."
  • Rule 2 - "G may soften to /j/ only when... 
  • Rule 4 and Rule 12.1 - vowel "name" changed to "long sound"
  • Spelling Rule 6 - "When a one-syllable word ends in a single-vowel Y, it always says /ī/."
  • Rule 14 - "accented" changed to "stressed" 
  • Rule 21 - "occasional nouns" changed to "some nouns"
  • Rule 27 - "does not say its name" changed to, "says its short or broad sound" 
• More About the Basic Phonograms (Appendix C): several updates and corrections in word lists. 
• New advanced phonograms were added.
• In pronunciation symbols, the vowel sound in do, soon, and flute is now written /ö/, rather than /oo/.
