In this English spelling question, four alternative spellings of the same word are given, and you must identify the correct standard spelling of the word meaning irritation or slight anger: select the correctly spelt word.

Introduction / Context:
This question assesses your understanding of English spelling, particularly for common emotion related nouns. The intended word here is the noun that refers to a feeling of irritation or mild anger. Spelling questions of this type are common in competitive examinations because they check both familiarity with everyday vocabulary and attention to detail in letter patterns within words.

Given Data / Assumptions:

• Four possible spellings are provided: Anoyance, Annoyanse, Anoyanse, and Annoyance.
• You must select the correctly spelt standard English word.
• The target meaning is the feeling of being irritated or slightly angry.
• All options are visually similar, with small variations in the number of n letters and the vowels used.

Concept / Approach:
The concept involved is recognition of the correct spelling of the familiar noun “Annoyance.” The verb is “annoy,” meaning to irritate, and the noun form is created by adding the suffix “ance,” forming “annoyance.” Any change in the number of n letters or in the vowel sequence before or after the suffix will produce a misspelling. A systematic approach involves comparing each option against the known base verb “annoy” and the known suffix “ance.” If either part is altered, the spelling becomes incorrect.

Step-by-Step Solution:
Step 1: Identify the base verb “annoy,” which is spelled a n n o y.Step 2: Recall that the noun form is created by adding the suffix “ance,” producing “annoyance.”Step 3: Examine option D, “Annoyance,” and notice that it preserves both the base “annoy” and the suffix “ance” correctly.Step 4: Check option A, “Anoyance,” which contains only one n in the beginning, making it a misspelling.Step 5: Look at option B, “Annoyanse,” where the ending is “anse” instead of “ance,” so the vowel is wrong.Step 6: Observe option C, “Anoyanse,” where both the number of n letters and the ending are incorrect.Step 7: Conclude that only “Annoyance” is correctly spelt.

Verification / Alternative check:
You can further verify the answer by recalling how the word appears in books, articles, or formal writing. The spelling “Annoyance” is the only one that looks familiar and is widely recognised. A dictionary check would confirm that “Annoyance” is the standard spelling for the noun meaning irritation, while the other three forms are not listed as standard words. Also, because “annoy” already has a double n, it is logical that the derived noun retains the double n at the start and adds the common noun suffix “ance.”

Why Other Options Are Wrong:
Anoyance is incorrect because it loses one of the n letters and does not match the base verb “annoy.” Annoyanse is wrong because the final syllable “anse” is not the standard suffix and changes the pronunciation. Anoyanse is doubly incorrect, as it reduces the double n to a single n and introduces the wrong ending. None of these forms matches the standard spelling or pronunciation used in educated English.

Common Pitfalls:
Learners often confuse suffixes such as “ance,” “ence,” and “anse,” and may rely only on sound instead of remembering the correct letter pattern. Another pitfall is ignoring the structure of the root word when forming derivatives, which leads to losing or adding letters incorrectly. In fast paced exams, candidates may also choose an option that looks vaguely familiar without carefully checking each letter. To avoid these mistakes, always think of the root word and the common suffix, and read the entire word slowly before deciding.

Final Answer:
The correctly spelt word among the options is Annoyance.
