In the following question, four spellings of a word are given. Choose the correctly spelt word which is the standard English spelling of the verb “possess” in the third person or in noun form.

Introduction / Context:
This spelling question focuses on the correct form of the word based on the verb “possess”. Spelling of words with double consonants and added endings is a common source of error in exams and everyday writing. The word “possesses” appears frequently in descriptions of ownership, characteristics, and abilities, so using the correct spelling is important for professional communication.

Given Data / Assumptions:
Options given: “poseses”, “posesses”, “possesses”, and “posseses”. The task is to identify which spelling matches the correct English form derived from “possess”. We assume the base verb “possess” is known and correctly spelt with a double “s”.

Concept / Approach:
The base form is “possess”. When forming the third person singular present (“he possesses”) or the noun form that refers to more than one act of possessing in some contexts, the spelling rules for verbs ending in “s” require us to add “es”. Since “possess” already has a double “s”, we add “es” directly, giving “possesses”. Therefore, we are looking for the pattern “possess” plus “es” with all consonants correctly doubled.

Step-by-Step Solution:
Step 1: Recall the base verb “possess”. It has the structure p o s s e s s. Step 2: To form the present tense third person singular, add “es” to get “possesses”. Step 3: Check option (c): “possesses” matches this exactly: p o s s e s s e s. Step 4: Check option (a): “poseses” drops one “s” and changes the pattern, which no longer reflects the base word. Step 5: Check option (b): “posesses” contains only one double “s” and misses one “s” where the base has two. Step 6: Check option (d): “posseses” again misplaces the double “s” and omits another, so it does not correctly represent “possess”.

Verification / Alternative check:
Check real usage: “The company possesses vast experience in the market.” In print and online sources, this spelling remains consistent. A good way to verify is to mentally remove the ending “es”. Removing “es” from “possesses” correctly recovers the base “possess”. If we attempt the same with “posesses” or “posseses”, the remaining letters do not form the valid base verb, which confirms those forms are incorrect.

Why Other Options Are Wrong:
“Poseses” removes one of the necessary “s” letters and does not reflect the original double “s” in “possess”.
“Posesses” rearranges the double “s”, resulting in a form that does not match the base spelling when the ending is removed.
“Posseses” or similar variants can appear plausible to the eye but are not supported by dictionaries or standard usage.
Only “possesses” correctly maintains the structure of the root and adds the appropriate ending.

Common Pitfalls:
Many learners struggle with words that have repeated consonants, especially “s”, “l”, and “t”. They may add or remove an “s” because the sequence looks crowded on the page. To avoid this, always start by writing or visualizing the root word and then attaching the suffix “es” or “ed” as needed. Regular exposure to correct spellings through reading also greatly reduces such errors.

Final Answer:
The correctly spelt word is possesses.
