Orthography and Spelling Rules Flashcards

When adding the suffix '-ing' to the word 'begin' (beGIN), the final consonant is doubled to form 'beginning.' However, when adding '-ing' to 'open' (OPen), the result is 'opening' — no doubling. Which orthographic principle governs this difference?

Answer: Consonant doubling in multisyllabic words before a vowel suffix is conditioned by stress: the final consonant doubles only when the last syllable of the base word is stressed.

In multisyllabic words, the final consonant is doubled before a vowel suffix only when stress falls on the final syllable of the base word. 'Begin' is stressed on the second syllable (beGIN), so the 'n' doubles: beginning. 'Open' is stressed on the first syllable (OPen), so no doubling occurs: opening. This stress-conditioned rule distinguishes multisyllabic doubling from the simpler CVC rule applied to monosyllabic words.

A student is uncertain whether to write 'perceptible' or 'perceptable.' An advanced CALT explains the rule: the '-ible' suffix is used when the root is a bound morpheme derived from Latin that cannot stand alone as an English word. Which of the following examples INCORRECTLY applies this principle?

Answer: digestible (digest is a complete, free English word → should be 'digestable' by this rule)

The bound-morpheme rule predicts '-ible' for roots that cannot stand alone (audible, visible, edible) and '-able' for free morphemes that are complete words (comfortable, readable). However, 'digestible' and 'contemptible' are genuine exceptions: both 'digest' and 'contempt' are free English words, yet they take '-ible.' These anomalies reflect the words' direct borrowing from Latin ('-ibilis' forms) rather than productive English suffixation, and they must be taught explicitly as exceptions to the otherwise reliable principle.

The orthographic rule for spelling the /k/ sound states that 'ck' is used immediately after a single short vowel at the end of a syllable (e.g., back, neck, pick). Which of the following sentences MOST accurately describes when 'k' alone — rather than 'ck' — is the correct spelling for the same sound?

Answer: 'k' follows a consonant, a vowel digraph, or a long vowel pattern; 'ck' is reserved for the position immediately after a single short vowel.

The distribution of 'k' versus 'ck' is phonologically conditioned. 'ck' appears exclusively after a single short vowel at the close of a syllable (back, deck, sick, rock, duck). In all other coda positions — after a consonant (milk, bank, silk), after a vowel digraph (book, seek, steak), or after a long vowel pattern (bike, flake) — 'k' alone is used. This rule also explains medial spellings: 'picnic' uses 'c' twice rather than 'ck' because the /k/ in the second syllable does not follow immediately after a short vowel in final position.

A student misspells the word 'definition' because the second vowel sounds like a schwa and provides no phonological cue to its identity. Which instructional strategy most directly leverages the structural consistency of English spelling to resolve this difficulty?

Answer: Guide the student to find a morphologically related word in which the same vowel is stressed and phonetically clear, then transfer that vowel letter to the derived form.

Morphological analysis is the most powerful tool for resolving schwa spellings. The vowel in the second syllable of 'definition' is /ə/, but the morphologically related word 'define' places stress on that same vowel (de-FINE), revealing it as 'i.' Similarly, 'competition' → 'compete' exposes the 'e,' and 'mental' → 'mention' exposes the 'e.' This strategy exploits the fact that English orthography preserves morpheme identity across stress-alternating derivational pairs, making the spelling predictable once the base form is identified.

The Floss Rule states that the letters f, l, s, and z are doubled at the end of a one-syllable word after a single short vowel (cliff, bell, grass, buzz). A CALT teaching this rule to an advanced student should explicitly address which of the following genuine exceptions?

Answer: 'if,' 'is,' 'bus,' and 'gas' — one-syllable words with a short vowel before /f/ or /z/ or /s/ that do NOT follow the doubling pattern

While 'off,' 'ill,' and 'add' follow the Floss Rule, 'if,' 'is,' 'bus,' 'gas,' 'yes,' 'plus,' 'pal,' 'nil,' and 'gel' are established exceptions: all are monosyllabic, end in /f/, /z/, or /s/ after a short vowel, yet do NOT double the final consonant. These high-frequency words — mostly of Anglo-Saxon or Latin origin — must be taught explicitly to prevent overgeneralization. Failing to address them leads students to misspell common words as 'iff,' 'iss,' or 'buss' (though 'buss' is actually a separate archaic word meaning 'to kiss').

The standard rule states that silent 'e' is dropped before vowel suffixes (hope + ing = hoping). However, in 'noticeable' and 'courageous,' the silent 'e' is RETAINED before the vowel suffixes '-able' and '-ous.' What is the orthographic rationale for retaining the 'e' in these cases?

Answer: The silent 'e' after 'c' or 'g' must be retained before the vowel suffix when the suffix begins with 'a' or 'o,' because dropping the 'e' would cause the soft consonant to revert to its hard pronunciation.

The letters 'c' and 'g' are soft (/s/ and /dʒ/) before the vowels 'e,' 'i,' and 'y,' but hard (/k/ and /ɡ/) before 'a,' 'o,' and 'u.' When the suffix '-able' or '-ous' (beginning with 'a' or 'o') is added to a word ending in '-ce' or '-ge,' the silent 'e' must be retained to protect the soft consonant: 'notice + able' → 'noticeable' (without 'e,' 'noticable' would have a hard /k/); 'courage + ous' → 'courageous' (without 'e,' 'couragous' would have a hard /ɡ/). When the suffix begins with 'e,' 'i,' or 'y,' the e can be dropped since those vowels themselves signal soft pronunciation (e.g., 'notice + ing' = 'noticing').
