Where and When [sh] is Spelled <t>

1. Is [sh] ever spelled <t> at the beginning of a word? No Is [sh] ever spelled <t> at the end of a word? No

2. Here are some words in which [sh] is spelled <t>. In each word mark the two letters following the <t> that spells [sh], either ‘$\mathrm{v}$’ or ‘$\mathrm{c}$’ for vowel or consonant, as we have done with ambition:

$&\text{ambition} && \text{partial} && \text{contribution} && \text{indignation}\\&\quad \text{vv} && \quad \text{vv} && \quad \text{vv} && \quad \text{vv}\\&\text{association} && \text{quotient} && \text{repetition} && \text{constitution}\\&\quad \text{vv} && \quad \text{vv} && \quad \text{vv} && \quad \text{vv}\\&\text{conventions} && \text{proportion} && \text{affectionately} && \text{restrictions}\\&\quad \text{vv} && \quad \text{vv} && \quad \text{vv} && \quad \text{vv}\\&\text{fractions} && \text{subtraction} && \text{prescription} && \text{quotation}\\&\quad \text{vv} && \quad \text{vv} && \quad \text{vv}\\&\text{deletion} && \text{impatience} && \text{reception} && \text{immigration}\\&\quad \text{vv} && \quad \text{vv} && \quad \text{vv} && \quad \text{vv}$

3. You should have found that in every word there was always the same pattern following the <t>. Was it CC, CV, W, or VC? VV

4. Whenever <t> spells [sh] it is always followed by two vowels. The vowel right after the <t> is always the same one. What is it? $\underline{}$

5. Whenever [sh] is spelled <t>, the <t> is always followed by two vowels, and the first of the two vowels is always an $<\mathrm{i}>$ . That pattern explains why <t> spells [t] in the first word in each of the following pairs but it spells [sh] in the second word:

<t> spells [t] <t> spells [sh]
native n$\acute{\mathrm{a}}$tion
receptive rec$\acute{\mathrm{e}}$ption
parting p$\acute{\mathrm{a}}$rtial
deleted del$\acute{\mathrm{e}}$tion
immigrated immigr$\acute{\mathrm{a}}$tion
fractal fr$\acute{\mathrm{a}}$ction
affecting aff$\acute{\mathrm{e}}$ction

6. In the words in the right column above is the <t> always followed by an $<\mathrm{i}>$ and another vowel? Yes In the words in the left column is the <t> ever followed by an $<\mathrm{i}>$ and another vowel? No

7. In the right column what sound does <t> spell? [sh] In the left column what sound does <t> spell? [t]

8. In each of the words in the right column, mark the vowel that has heavy stress, as we have done with nation. Does the $<\mathrm{i}>$ and the next vowel after the <t> that spells [sh] ever have heavy stress on it? No

When [sh] is spelled <t>, the two vowels after the <t> will always be unstressed.

9. In each of the following words [sh] is spelled <t> and each one ends with the suffix -ion. Analyze each word into its stem and -ion, showing any changes that occurred when the stem and suffix combined. Most of the stems are free, but one is bound. Be sure to show any final <e> deletions:

Word = Stem + Suffix -ion
legislatio = legislat$\cancel{e}$ + ion
indication = indicat$\cancel{e}$+ ion
calculation = calculat$\cancel{e}$+ ion
restriction = restrict + ion
contribution = contribut$\cancel{e}$+ ion
appreciation = appreciat$\cancel{e}$+ ion
precaution = precaut + ion

Teaching Notes.

As was said in the Teaching Notes to Lesson 40, the trigger here is the unstressed $<\mathrm{i}>$ following the <t>: When the $<\mathrm{i}>$ is followed by another unstressed vowel, the $<\mathrm{i}>$ tends to simplify to a [y]-glide. Articulating a [y]-glide tends to pull the tongue back to the palate, which leads to [tsh] and ultimately [sh]. The sequence is [ti] > [ty] > [tsh] > [sh]. There are a very few holdouts worth mentioning:
