Morphology and Etymology Flashcards

A CALT is teaching a student why 'offer,' 'oppose,' and 'occur' are spelled the way they are. Which explanation MOST accurately describes the morphological phenomenon at work?

Answer: The prefix 'ob-' assimilates to match the place of articulation of the following consonant, producing of-, op-, and oc- respectively

The Latin prefix 'ob-' (meaning 'toward, against') assimilates regressively to match the place of articulation of the base-initial consonant: ob- + ferre → offer (bilabial), ob- + ponere → oppose (bilabial stop), ob- + currere → occur (velar). This is the same assimilation process seen with ad-, in-, com-, and sub-, and explaining it etymologically helps students understand why doubling occurs in these Latinate words.

A student asks why 'island' has a silent 's' when no related word—'isle,' 'islet'—seems to justify it. Which etymological explanation is MOST accurate?

Answer: The 's' was inserted by 16th-century scholars who incorrectly connected the word to Latin 'insula,' even though 'island' derives from Old English 'iegland' and is unrelated

'Island' derives from Old English 'iegland' (ieg = water-meadow/island + land), with no 's' in its history. Renaissance scholars mistakenly associated it with Latin 'insula' and inserted the 's' by analogy—a classic case of false or folk etymology reshaping spelling. This is a critical teaching point: not every silent letter marks a historically pronounced phoneme; some are hypercorrections. Contrast with 'isle,' which genuinely derives from Latin 'insula' via Old French 'isle' and legitimately retains the 's.'

In morphological analysis, the element '-ceive' in 'perceive,' 'deceive,' 'conceive,' and 'receive' is BEST classified as which type of morpheme?

Answer: A bound base morpheme derived from Latin 'capere/cipere' (to take, seize), which appears in allomorphic forms including -cept- and -cap-

'-ceive' is a bound base—it cannot stand alone and carries lexical meaning (to take/seize) only in combination with prefixes. It is an allomorph of the Latin root 'cap-/cip-' (capere = to take), which surfaces as -ceive (receive), -cept (reception), -cap (capable, capture), and -cip (recipient, incipient) depending on phonological environment and affixation. Recognizing allomorphic variation in bound bases is an advanced morphological skill essential for CALT practice when teaching vocabulary and spelling across the Latinate layer.

Which statement MOST precisely describes a structural difference between Greek and Latin combining patterns that a CALT should teach when introducing polysyllabic vocabulary?

Answer: Greek elements typically join with the connecting vowel '-o-' (as in 'biography,' 'photograph'), while Latin elements generally join bases directly or use '-i-' as a linking vowel (as in 'carnivore,' 'agriculture')

Greek compound morphology characteristically uses '-o-' as a connecting vowel between elements: bio+o+graphy, photo+o+graph, micro+o+scope. Latin compounds typically connect bases directly (corp+us+cle → corpuscle) or use '-i-' as a linking vowel in compound forms (agr+i+culture, carn+i+vore, omn+i+vore). This distinction helps students identify the etymological layer of a word and predict spelling, since Greek '-o-' linking is highly consistent. Exceptions (e.g., 'ped+i+atrics' using Greek 'pais/paidos') require explicit teaching.

When 'electric' becomes 'electricity,' the final /k/ of the base shifts to /s/. How should a CALT MOST accurately characterize this change for instructional purposes?

Answer: This is a morphophonemic change (velar softening) in which the phoneme /k/ alternates with /s/ when followed by a Latinate suffix beginning with a front vowel, reflecting a Latin-to-French sound shift preserved in English

The /k/ → /s/ alternation before Latinate suffixes beginning with front vowels (-ity, -ious, -ial, -ify) is called velar softening—a morphophonemic rule inherited from Latin and reinforced through Old French. It is phonemic, not merely orthographic: the underlying phoneme /k/ actually changes to /s/ (electric /ɪˈlɛktrɪk/ → electricity /ɪˌlɛkˈtrɪsɪti/). This differs from option A's claim of a purely graphemic rule. CALTs should teach this as a predictable morphophonemic pattern across the Latinate layer: critic/criticism, music/musician, magic/magician.

The word 'sovereign' contains a silent 'g' that does not appear in its Old French source 'soverain.' Which etymological process BEST accounts for this intrusive letter?

Answer: The 'g' was inserted analogically by association with the word 'reign' (from Latin 'regnare/regnum'), even though 'sovereign' and 'reign' are etymologically unrelated

'Sovereign' entered English from Old French 'soverain' (ultimately from Vulgar Latin *superanus), which contains no 'g.' The silent 'g' was inserted by analogy with 'reign' (Latin regnare, regnum), a completely separate etymological line in which the 'g' is genuinely connected to the Latin root. This process—introducing a letter from one word into an unrelated word by perceived similarity—is called analogical reformation or orthographic contamination. It is an important concept for CALTs because it explains why some silent letters cannot be decoded from a word's own history and must be taught explicitly alongside their etymological neighbor.
