From the following options, select the word that is correctly spelt in standard English.

Introduction:
This spelling question checks whether you can identify the single correctly spelt word among several similar looking distractors. Correct spelling is tested frequently in English sections and is particularly important for formal writing. Three of the options are slightly altered forms of real words, while one matches the standard spelling exactly.

Given Data / Assumptions:

- Options: deceased, choiciest, anglecan, thankfull. - Only one of these is spelled according to standard English rules. - The others contain extra letters or incorrect letter patterns.

Concept / Approach:
The word deceased is a common adjective and noun meaning dead or no longer living. Its correct spelling is d e c e a s e d. The word choiciest should actually be spelled choicest, the superlative form of choice. Anglecan is a distorted form of Anglican, which refers to the Church of England or its members. Thankfull is an incorrect variant of thankful, which has only one l at the end. Therefore, deceased stands out as the only fully correct option.

Step-by-Step Solution:
Step 1: Look at deceased and recall that it is a standard word used in legal and everyday contexts, such as the deceased person. Step 2: Check choiciest and remember that the usual spelling of the superlative is choicest, not choiciest. Step 3: Examine anglecan and recognise that the recognised term is Anglican. Step 4: Consider thankfull and recall that the correct form is thankful, with a single l at the end. Step 5: Conclude that deceased is the only correctly spelt word.

Verification / Alternative check:
Imagine example sentences: The deceased left no will or The deceased person's property will be distributed according to law. These sentences look and sound natural. If you attempt to use choiciest, anglecan, or thankfull in a formal text, they would be marked as spelling errors. Checking a dictionary would further confirm that deceased appears as such, while the other forms do not.

Why Other Options Are Wrong:
Choiciest has an unnecessary extra letter i and does not match the normal pattern of forming a superlative. Anglecan changes the vowel order and consonants from the correct word Anglican. Thankfull incorrectly doubles the final l, which is not required. Because exam questions demand strict correctness, these forms must be rejected.

Common Pitfalls:
Students often read quickly and assume that words that look familiar must be correct, even if they contain small alterations. To avoid such traps, slow down for a moment and mentally compare each option with how you have seen it in books, newspapers, or on reputable websites. Building a habit of reading quality English material regularly will strengthen your internal sense of correct spelling and make these questions easier over time.

Final Answer:
deceased is the correctly spelt word among the given options.
