In the following question, four words are given out of which one word is incorrectly spelt. Select the word that is spelt incorrectly.

Introduction / Context:
Spelling questions assess your familiarity with standard English spellings for common words. Here, you are given four words and must identify the one that is spelt incorrectly. The other three are spelt correctly. This type of question is common in competitive exams because many English words have tricky letter sequences that learners often confuse.

Given Data / Assumptions:
- Options: Autumn, Desperate, Reciept, Traffic. - Exactly one of these spellings is incorrect. - We must recognise the standard dictionary spelling of each word.

Concept / Approach:
The words autumn, desperate and traffic are all common and have fixed spellings. The word related to a written acknowledgment for money paid is spelled receipt, with the letters e i after c. The option Reciept reverses the order of i and e, which is a frequent mistake by learners. The approach is to check each word against the form you have seen in reading, keeping in mind that misplacing i and e is a common trick in exam questions.

Step-by-Step Solution:
Step 1: Examine Autumn. Autumn is correctly spelt a u t u m n, with a silent n at the end. The given option matches this spelling. Step 2: Examine Desperate. Desperate is correctly spelt d e s p e r a t e, and the option Desperate is written in this way, so it is correct. Step 3: Examine Reciept. The standard spelling for this word is receipt, r e c e i p t. The option swaps the positions of e and i, giving r e c i e p t, which is wrong. Step 4: Examine Traffic. Traffic is correctly spelt t r a f f i c, and the option Traffic matches this spelling. Step 5: Since only Reciept differs from the correct form, it is the incorrectly spelt word.

Verification / Alternative check:
Think about where you have seen these words. Autumn appears in seasons of the year, desperate in phrases like desperate attempt, and traffic in daily news. Their spellings in newspapers, books and signs match the given options. The word for the written acknowledgment of payment appears on bills and slips as receipt, never as reciept. Visual memory of actual receipts and printed forms reinforces that the correct form has e before i after c in this word. Therefore, Reciept is confirmed as the incorrect spelling.

Why Other Options Are Wrong (as answers):
Autumn is not the wrong spelling because it correctly includes the silent n at the end. Desperate is not the wrong spelling because it correctly uses e before r and a before t in its last syllables. Traffic is not the wrong spelling because it correctly doubles the f and ends with ic.

Common Pitfalls:
Many learners struggle with the i and e combination, especially after c. A famous guideline is the rule i before e except after c, although there are exceptions. Receipt follows this pattern and is spelled r e c e i p t. Exam setters exploit this confusion by presenting wrong forms like reciept. To reduce errors, pay special attention to such patterns while reading and make a note of frequently used but commonly misspelt words like receipt, believe, friend and ceiling.

Final Answer:
The incorrectly spelt word is Reciept; the correct spelling is receipt.
