Difficulty: HardVerb and Adverb Suffixes

Match each suffixed word with the precise semantic transformation and grammatical role produced by its verb or adverb suffix.

  • nullifyConverts an adjective designating invalidity into a causative verb meaning 'to make void or legally ineffective'.
  • lengthwiseConverts a noun measuring linear dimension into an adverb describing orientation along that dimension.
  • heartenConverts a noun denoting spirit or vital emotion into a transitive verb meaning 'to encourage or cause to gain resolve'.
  • leewardConverts a nautical noun indicating shelter into a directional adverb meaning 'toward the side sheltered from wind'.

Answer

nullify matches the causative verb transformation to make void; lengthwise matches the adverb transformation describing orientation along a linear dimension; hearten matches the verb transformation to encourage or cause to gain resolve; leeward matches the directional adverb transformation toward the side sheltered from wind.
Each pair correctly matches the base root and derivative suffix to its precise semantic output: '-ify' and '-en' generate causative verbs ('nullify', 'hearten'), while '-wise' and '-ward' generate manner and directional adverbs ('lengthwise', 'leeward').

Step-by-Step Solution

1
Isolate the base root and suffix of each target word to determine the base part of speech and affix category.
'null-ify' (adjective + verb suffix), 'length-wise' (noun + adverb suffix), 'heart-en' (noun + verb suffix), and 'lee-ward' (noun + directional adverb suffix).
Morpheme segmentation identifies whether the affix functions to create an action/state (verb) or a manner/direction (adverb).
2
Analyze the semantic effect of the verb-forming suffixes '-ify' and '-en'.
'-ify' indicates causation or making into a state ('to make void/null'), while '-en' attaches to 'heart' to denote causing courage or spirit.
Differentiating verb suffix functions prevents confusing Latinate causative morphemes with Germanic transitive affixes.
3
Analyze the semantic effect of the adverb-forming suffixes '-wise' and '-ward'.
'-wise' specifies manner or dimensional orientation ('in the direction of length'), whereas '-ward' explicitly denotes spatial movement or heading toward shelter ('lee').
Both create adverbs, but '-wise' modifies respect/manner/dimension while '-ward' specifies spatial heading.
4
Pair each analyzed morpheme compound with its exact semantic definition.
All four items map unambiguously to their corresponding grammatical role definitions.
Confirms complete morphological and syntactic alignment without overlap.

Key Concept

Derivational verb suffixes (-ify, -en) and adverb suffixes (-wise, -ward) systematically shift base roots into specific syntactic categories with distinct causative or directional meanings.
