In the following spelling question, four English words are given; choose the one that is incorrectly spelt and therefore not acceptable in standard written English.

Introduction / Context:
This question again tests spelling, an area where many candidates lose easy marks. The ability to recognise standard spellings of frequently used formal words reflects careful reading habits and attention to detail. Exams often include one incorrectly spelt word among several correct ones, and your task is to spot the odd one out by relying on your familiarity with correct forms.

Given Data / Assumptions:
We are given four words: "Abhorrent", "Abstinent", "Achievement", and "Accruemant". We must identify which one is wrongly spelt. We assume standard English spelling as used in academic and professional contexts.

Concept / Approach:
The words "abhorrent" (disgusting or loathsome), "abstinent" (refraining from indulgence), and "achievement" (accomplishment) are all correctly spelt. The problem lies with "Accruemant". The correct noun form from the verb "accrue" is "accruement" or more commonly "accrual". The spelling "Accruemant" is incorrect because of the ending "-mant" instead of "-ment".

Step-by-Step Solution:
Step 1: Read each word carefully, focusing on common suffixes such as "-ment" and "-ent". Step 2: Recognise that "abhorrent", "abstinent", and "achievement" are familiar and correctly formed from their roots. Step 3: Look at "Accruemant" and notice that the usual pattern would be "accruement" if that form is used at all. Step 4: Confirm that the unusual ending "-mant" signals a spelling error. Step 5: Select Option D as the incorrectly spelt word.

Verification / Alternative check:
You can verify by recalling that many nouns formed from verbs end in "-ment": "achievement", "development", "improvement", and so on. Following this pattern, "accrue" would form "accruement". The given word "Accruemant" does not follow this rule and is not found in standard dictionaries. Meanwhile, "abhorrent", "abstinent", and "achievement" appear frequently in formal writing with exactly those spellings, confirming that Option D alone is wrong.

Why Other Options Are Wrong:
Option A, "Abhorrent", is correctly spelled and means causing disgust or hatred. Option B, "Abstinent", correctly refers to someone who refrains from indulgence, especially in food or drink. Option C, "Achievement", is the standard spelling for a thing done successfully, typically by effort, courage, or skill. Since they are all correctly spelt, they cannot be selected as the erroneous word. Only Option D violates the usual spelling rules and accepted usage.

Common Pitfalls:
Some candidates may doubt "abhorrent" or "abstinent" because these words are less common in everyday conversation. Others may skim quickly and not notice the subtle change from "-ment" to "-mant" in "Accruemant". The safest approach is to break words into root and suffix and compare them with known patterns. Regular reading of editorials and standard texts reinforces correct spellings and makes such questions much easier to handle.

Final Answer:
The correctly identified incorrectly spelt word is "Accruemant".
