Morphology and Etymology Flashcards

A student spells 'impatient,' 'illegal,' 'irregular,' and 'impossible' correctly but writes 'inlogical' and 'inpossible' on a different task. Which morphophonological process explains the standard spelling variations of the negative prefix, and what specifically drives it?

Answer: Assimilation — the prefix adapts its final consonant to match the place of articulation of the following consonant

The negative prefix 'in-' undergoes assimilation: before bilabials /p, b, m/ it becomes 'im-'; before /l/ it becomes 'il-'; before /r/ it becomes 'ir-'. The nasal consonant shifts its place of articulation to match the following consonant. This is a classic example of progressive assimilation driven by phonological environment, not deletion or insertion of sounds.

In morphological analysis, a 'cranberry morpheme' (unique morpheme) is best characterized as which of the following?

Answer: A bound morpheme that appears in only one lexical item and carries no independently assignable semantic meaning

A cranberry morpheme (named after the 'cran-' in 'cranberry') is a bound morpheme that is morphologically identifiable — it recurs in at least one related form — but has no transparent, assignable meaning on its own. 'Cran-' cannot be defined in isolation. Other examples include 'twi-' in 'twilight.' This concept is important for language therapists when teaching morpheme awareness, as students may search for meaning where none is independently recoverable.

A 12-year-old with dyslexia consistently writes 'goed,' 'runned,' and 'swimmed' for past-tense forms. His errors on 'went,' 'ran,' and 'swam' reflect a specific morphological phenomenon distinct from typical over-regularization. Which concept MOST precisely names the underlying challenge with forms like 'went'?

Answer: Suppletion — 'went' derives from an etymologically unrelated root (Old English 'wendan'), making the paradigm internally unpredictable

Suppletion occurs when inflected forms of a word come from etymologically distinct roots rather than from phonological or morphological modification of a single base. 'Went' was originally the past tense of 'wend' (to travel) and was borrowed into the 'go' paradigm; there is no morphological rule connecting 'go' and 'went.' This is qualitatively different from ablaut (e.g., 'run/ran'), where a vowel alternation pattern is at least partially regular across verb classes.

An academic language therapist is teaching why 'sign,' 'benign,' and 'malign' contain a silent , while 'signal,' 'benignant,' and 'malignant' do not. Which principle MOST accurately accounts for retaining in the silent-consonant forms?

Answer: Morphological transparency — the spelling preserves a visible connection to morphologically related forms where is pronounced, supporting recognition of the shared base

English orthography often preserves morphological relationships at the cost of phonological regularity. The in 'sign' is silent in isolation, but it is pronounced in 'signal,' 'signature,' and 'signify.' Retaining the in 'sign' makes the morphological family visually cohesive — a direct instructional asset for language therapists teaching word families. This principle, sometimes called 'morphological conservatism' in English spelling, explains many silent letters (e.g., 'bomb/bombard,' 'muscle/muscular').

The suffix '-ity' (as in 'ability,' 'clarity,' 'hostility') and the suffix '-ness' (as in 'darkness,' 'happiness') both form abstract nouns from adjectives. Which statement MOST accurately distinguishes their morphological behavior in English?

Answer: '-ness' is a Germanic suffix that attaches productively to virtually any adjective, while '-ity' is a Latinate suffix whose attachment is largely lexically conditioned and non-productive with new coinages

'-ness' is a highly productive Germanic suffix that can be appended to virtually any adjective, including novel or nonce adjectives (e.g., 'zoomy-ness,' 'cringey-ness'). '-ity,' by contrast, is a Latinate nominalizer whose distribution is largely lexically listed — we say 'hostility' not 'hostileness,' but we cannot coin 'zoomy-ity.' This Germanic vs. Latinate productivity asymmetry is a critical pattern for CALT practitioners teaching derivational morphology to students, as it predicts which words follow transparent suffix rules and which must be memorized.

In teaching bound morphemes, a therapist notes that the Latin root 'rupt' (break) appears in 'disrupt,' 'interrupt,' 'corrupt,' and 'erupt.' A student asks why 'bankrupt' does not follow the same pattern semantically. What is the MOST etymologically accurate explanation?

Answer: 'Bankrupt' is a false cognate — it derives from a Germanic root meaning 'broken bench' ('banco rotto' in Italian), and the 'rupt' ending is a coincidental phonological overlap, not the Latin morpheme 'rupt'

Despite its spelling, 'bankrupt' does NOT contain the Latin morpheme 'rupt' meaning 'break.' It derives from Italian 'banca rotta' (broken bench/counter — the bench of a moneylender who could no longer pay was literally broken as a public sign of failure), borrowed into English via French. The '-rupt' spelling is a folk-etymological reshaping that makes the word look like it contains the Latin morpheme, but the historical source is 'rotta' (broken, from 'rompere'). This is an important caution for language therapists: morphological pattern instruction must be paired with etymological accuracy to avoid teaching false generalizations.
