In the following question, four words are given. Identify the one word that is incorrectly spelt according to standard English usage.

Introduction / Context:
Spelling items focus on small but important details of English words, such as doubled consonants and vowel order. Here, four common words are shown, and we must select the one which is not spelled correctly. Examinations often select a word like “receding” because its pronunciation can mislead learners into inserting extra vowels or consonants.

Given Data / Assumptions:
- The options are: Receeding, Cemetery, Parallelogram, Rehearsal, and an implicit correct form Receding for comparison.
- Only one spelling is wrong according to standard English.
- The others are standard dictionary spellings.

Concept / Approach:
We need to remember that spelling in English is not always phonetic. Therefore, we must rely on prior reading and memorization of the correct forms. Words like “cemetery” and “parallelogram” are often tested because they mix vowels and consonants in ways that are not obvious from pronunciation. The strategy is to check each option carefully against what you know from exposure to written English.

Step-by-Step Solution:
Step 1: Consider option B: “Cemetery”. The correct spelling of the burial ground is c-e-m-e-t-e-r-y. The option matches this exactly, so it is correct. Step 2: Consider option C: “Parallelogram”. This geometrical term is spelt p-a-r-a-l-l-e-l-o-g-r-a-m. The option has the correct pattern of double l and is therefore correctly spelt. Step 3: Consider option D: “Rehearsal”. The correct spelling of the noun related to practice before a performance is r-e-h-e-a-r-s-a-l, which is the same as in the option. Step 4: Consider option A: “Receeding”. The correct form of the verb in its present participle is “receding”, spelt r-e-c-e-d-i-n-g, with one e after c and one after d. The option “Receeding” with double e after c is incorrect. Step 5: Conclude that option A is the only incorrectly spelt word of the given set.

Verification / Alternative check:
A standard dictionary confirms that “receding” (as in receding hairline or receding tide) uses the base verb “recede”, which has the ending -cede, not -ceed. This explains why “Receeding” is wrong: it wrongly follows the pattern of words like “proceeding”, but “recede” belongs to a different spelling family. The other words exactly match their dictionary forms.

Why Other Options Are Wrong:
Again, “wrong” here means wrong to choose as the incorrect spelling, because:
- Cemetery: has the vowels e-e-e in that exact sequence, which is correct.
- Parallelogram: correctly shows “parallel” plus “ogram”.
- Rehearsal: correctly spells the noun based on the verb “rehearse”.

Common Pitfalls:
A frequent mistake is to confuse “recede” with verbs ending in -ceed, leading to spellings like “receed” or “receeding”. The safest habit is to learn word families: proceed, proceed-ing; succeed, success; but recede, receding. When you know which family a word belongs to, you are less likely to introduce extra vowels.

Final Answer:
The incorrectly spelt word in this list is Receeding (correct form: “receding”).
