In this English vocabulary question on synonyms, choose the option that best expresses the meaning of the word "Felicity".

Introduction / Context:
This question belongs to the category of synonym based vocabulary items. You are asked to select the word that is closest in meaning to the given word "Felicity". Strong vocabulary skills are important for competitive exams, reading comprehension, and effective communication, so understanding words like "Felicity" helps you express ideas about happiness and good fortune precisely.

Given Data / Assumptions:

- Target word: Felicity. - Options: Bliss, Misery, Grief, Trouble, Suffering. - You must choose the closest meaning, not just a vaguely related word.

Concept / Approach:
The word felicity is a noun that means great happiness, intense joy, or blissful contentment. It can also mean a pleasing ability to express something well, but in common exam usage it primarily refers to happiness or bliss. Therefore, the correct option will have a positive meaning of great joy. Words that express sadness, difficulty, or pain are antonyms and must be rejected. Matching the emotional tone and core meaning is the key strategy here.

Step-by-Step Solution:

Verification / Alternative check:
Use the words in simple example sentences to confirm. "She was filled with felicity when she heard the good news" and "She was filled with bliss when she heard the good news" convey the same emotional picture of deep happiness. Sentences with misery, grief, trouble, or suffering would describe sadness or hardship, not joy. This simple substitution test shows that bliss is the proper synonym for felicity in this context.

Why Other Options Are Wrong:
Misery, grief, trouble, and suffering all have negative meanings. Misery is intense unhappiness, grief is deep sorrow, trouble refers to difficulties, and suffering refers to pain. None of them convey the pleasant, joyful feeling associated with felicity. In fact, they are closer to antonyms. Since the question clearly asks for a word that best expresses the meaning of felicity, these negative options must be eliminated.

Common Pitfalls:
A common error is to confuse felicity with facility because they sound somewhat similar. Facility means ease or skill in doing something, which is different from felicity. Another pitfall is selecting an option without fully recalling the meaning, just because it seems less negative than others. Always identify whether the word expresses a positive or negative feeling and match that with the given context.

Final Answer:
The word that best expresses the meaning of "Felicity" is "Bliss", so the correct answer is Bliss.
