Spelling [s]

About 97% of the time, [s] is spelled <s>, <c>, or <ss>.

We often use a silent final <e> to insulate a single <s> so that it does not come at the end of a base and look like an -s suffix, as in words like lapse and tense (compared to the plurals laps and tens). Very few free bases end in [s] spelled with a single <s>. The only common ones are this, bus, us, gas, canvas, chaos, sis, plus, and yes.

Usually when the <s> spelling of [s] comes at the very end of a word without the insulating final <e>, it is either the -s suffix, as in verbs like obstructs or plural nouns like contracts, or it is part of a suffix like -ous, -us, or -ics, as in words like courageousradius, and mathematics.

Examples

You can hear the sound [s] at the beginning, in the middle, and at the end of the word success. In success [s] is spelled three different ways: <s>, <c>, and <ss>.

[s] Spelled <ss>

The sound [s] is most often spelled <s>, but it is often spelled <ss>.

  1. Underline the <ss> spellings of [s] in the following words.

  2. Two of the twenty-four words above have <ss> because of the full assimilation of the prefix ad- when it was added to a stem that started with <s>. List the two below in the Words column and then analyze them into prefix plus stem and show the full assimilation. As you do them check them off the list above:

  3. It is rare for <ss> to be due to twinning, for so few free bases end in a single <s>. But three of the twenty-four words above have <ss> due to twinning. List them below, analyze them to show the twinning, and cross them off of the list above:

    Word Analysis: Stem + Suffix
       
       
       
  4. Four of the twenty-four words have <ss> due to simple addition when the prefix dis- or mis- was added to a stem that started with <s>. List them below, analyze them to show the simple addition, and cross them off of the list above:

  5. Although the sound [s] is never spelled <ss> at the beginning of words or elements, it is often spelled <ss> at the very end of words. Ten of the twenty-four words above end with <ss>. Five of them end with the same suffix. List those five below; analyze each into stem plus suffix or suffixes, and cross them of the list above:

  6. The remaining five words that end in <ss> all have short vowels right in front of the [s] so the <ss> spelling makes a regular VCC pattern. Write those five into the table below:

         
         
  7. Also, there should be five words remaining on your list of twenty-four words that contain <ss> in the middle; all five have short vowels in front of the [s]. Write the five words below and mark the VCC pattern in each one:

[s] Spelled <se> or <ss> at the End of Words

In English we tend to avoid ending words with a single <s> that comes at the end of a base. To keep the single <s> from coming at the end, sometimes we double the <s>. Sometimes we add a final <e>.

There are four very common bases that end <ss> and that often come at the end of words and free stems. Two of them are free bases: pass, with an original meaning “step, pace” and press, “press, squeeze.” Two of them are bound bases: cess, with an original meaning “go” and miss, with an original meaning “let go, cause to go.”

Examples

The final <s> is doubled in fuss and caress.

A final <e> is added to intense and impulse. In words like intense and impulse the final <e> is not marking a long vowel, or a soft <c>, a soft <g> or a voiced <th>. It is just insulating the <s>, keeping it from coming at the end of the base and word.

Review

  1. The following words all end with a base that itself ends with the sound [s]. In each case [s] is spelled <ss> or it is spelled <s> with an insulating final <e>. Words marked n. are nouns. Sort the words into the matrix.

Another Suffix with <ss>

In many words the sound [s] is spelled <ss> in the suffixes -less and -ness. Another suffix that ends <ss> is -ess, which adds the meaning “female, feminine” to nouns: host “male” + ess = hostess “female”

Sometimes, when -ess is added to a male noun that ends in the suffixes -er or -or, an unusual deletion occurs: waiter + ess = wait e r + ess = waitressactor + ess = act o r + ess = actress. In these cases when the -ess is added, we delete the <e> or <o> in front of the final <r>.

Today we are less anxious to distinguish between males and females in our words than people were in the past. Some people find words ending in -ess to be offensive, and many of the -ess words are falling out of use. But we still do use a number of words that contain -ess and thus the <ss> spelling of [s].

Examples

In the male nouns ending in -er or -or that you have worked with so far, the -ess was added to the male noun. Sometimes, however, the -ess is added to the same stem to which the -er or -or is added to form the male noun, as with the stem sorcer.

Stem Male Noun: Stem plus -er or -or Female Noun: Stem plus -ess

Review

Analyze each of the following nouns into stem noun and suffix. Show any changes that took place when the suffix and stem combined:

Noun = Stem Noun + Suffix
1. hostess host ess
2. lioness = +
3. goddess = +
4. princess = +
5. countess = +
6. poetess = +

Now try some the other away around. Add the suffix -ess to the stem nouns to form new nouns, showing any changes:

Stem Noun + Suffix = Noun
7. priest ess priestess
8. giant + =
9. steward + =
10. shepherd + =
11. prince + =
12. god + =

 Analyze the following words to show that change:

Noun = Stem Noun + Suffix
13. waitress wait e r ess
14. actress act o r ess
15. tigress = +
16. huntress = +
17. enchantress = +
18. eldress = +
19. tempter = +
20. mister = +

Write out the male and female nouns in the two right hand columns and be ready to talk about any changes that too place:

[s] Spelled <c> or <sc>

The sound [s] is spelled <s> or <ss> about eight times out of ten. The rest of the time it is usually spelled <c>.

The letter <c> spells the sound [s] only when it is followed by the letters <e>, <i>, or <y>. When the letter <c> spells the sound [s], it is called soft <c>.

Examples

Whenever <c> spells [s], there will be an <e>, <i>, or <y> following it. But the problem is that often [s] is spelled with an <s> with an <e>, <i>, or <y> after it, too. Read the following pairs of words aloud and look at how [s] is spelled in each of them:

sellcellsentcentserialcerealsitecitesymbolcymbal

Words like the ones in each of these pairs are called homophones. Homo- means “same,” and phone means “sound.” Homophones are two or more words that have the same sound but different meanings and spellings:

Rare Spellings of [s]

The sound [s] is spelled <s>, <ss>, or <c> just about all of the time. Occasionally it is spelled <sc>. On rare occasions, [s] is spelled <st>, <ps>, <sw>, and <z>.

Examples

In words like castle and fasten, where there is an <le> or an <en> right after the <st>, the <t> is not pronounced. It was pronounced a long time ago, but not anymore. Notice that we still pronounce the [t] in some words, like consistent or restless - though you can feel how hard it is to keep it in a word like restless. It is the loss of that earlier [t] that leads to the rare <st> spelling of [s].

The <ps> in psalmpsychology, and psychiatrist comes from the Greek letter psi,Ψ, pronounced [sī]. When Greek words were taken into Latin and English, psi was represented by <ps>. The <p> was pronounced long ago, but gradually it came not to be, which leads to the rare <ps> spelling of [s].

The <w> is not pronounced in answer because the [w] sound tends to drop out when it is weakly stressed and is followed by [r]. Notice that there is also no [w] in conquer, with a following [r], but there is one in conquest, with no following [r]. The same pattern holds in liquor and liquidAnswer is related to the word swear, in which the <w> is pronounced, because swear is usually stressed. Remembering the relationship with swear can help you remember to put the <w> in answer.

The <w> is not pronounced in sword because [w] is sometimes lost in front of certain vowel sounds. This is the same thing that led to our dropping the [w] sound in two.

The [s] in words like waltz and quartz comes from German. In German <z> is pronounced [ts]. So in these words [s] is spelled <z>.
