Spelling – Identify the one misspelled word among options A–D, or choose “All correct” if every option is correctly spelled. A) Grammer B) Hammer C) Manner D) Stammer

Introduction / Context:This question targets the common confusion between “-er” and “-ar” endings in English nouns, and distinguishing families with double “m” and “n”. Only one option is misspelled.

Given Data / Assumptions:

• Candidates: Grammar, Hammer, Manner, Stammer (presented forms vary).
• Phonetic clue: unstressed schwa endings may sound similar, but spelling families differ.

Concept / Approach:Words formed on the pattern gram-mar, ham-mer, man-ner, stam-mer exhibit consistent consonant doubling, but the vowel before “r” differs by lexical family. “Grammar” uniquely ends with “-ar”, not “-er”.

Step-by-Step Solution:

Verification / Alternative check:Remember the field of study is “grammar” (think “gram-mar rules”). Reputable dictionaries show “grammar” only; “grammer” is a common misspelling.

Why Other Options Are Wrong:

• Hammer: Correct common noun.
• Manner: Correct noun meaning way/style; distinct from “manor”.
• Stammer: Correct verb/noun related to disfluency.

Common Pitfalls:Over-generalizing the “-er” ending because many English agent nouns end with “-er”. “Grammar” is not an agent noun; it is from Greek “grammatika”.

Final Answer:Grammer
