In the following question, out of the four alternatives, select the word that is similar in meaning to the given word Loquacious.

Introduction / Context:
This vocabulary question asks you to choose a synonym for the adjective loquacious. This word appears often in reading passages and word lists used for competitive exams. It describes a certain kind of personality or speaking habit. To answer correctly, you must recall or infer what loquacious means and then select the option that best matches that meaning.

Given Data / Assumptions:
- Target word: Loquacious. - Options: Talkative, Foolishness, Graceful, Entertainer. - Only one option is an adjective that directly refers to speech or talking habits.

Concept / Approach:
Loquacious comes from a Latin root related to speaking. It is used for people who talk a great deal, often very freely. In everyday English, we would describe such a person as talkative or very chatty. Therefore, the correct synonym must capture the idea of talking a lot, not being foolish, graceful or connected with entertainment as a profession. Matching part of speech is also a useful clue: loquacious is an adjective, so a synonym is likely to be another adjective.

Step-by-Step Solution:
Step 1: Recall the meaning of loquacious: someone who tends to talk a great deal, often at length. Step 2: Examine Talkative. Talkative is an adjective that describes someone who likes to talk a lot. This directly matches the meaning of loquacious. Step 3: Examine Foolishness. This is a noun that refers to silly behaviour or lack of sense, and does not specifically describe talking a lot. Step 4: Examine Graceful. Graceful is an adjective describing elegance of movement or style and has no direct connection with speaking habits. Step 5: Examine Entertainer. This is a noun that describes a person whose job is to entertain others, often by singing, acting or telling jokes, but it does not simply mean talkative.

Verification / Alternative check:
Consider example sentences. We can say She is very loquacious in meetings or She is very talkative in meetings with essentially the same meaning. However, replacing loquacious with graceful or foolishness does not make sense: She is very graceful in meetings speaks about her movement or behaviour, and She is very foolishness in meetings is grammatically wrong. Calling someone an entertainer describes a role, not a speaking habit. These checks confirm that talkative is the only option that works as a synonym in typical contexts.

Why Other Options Are Wrong:
Foolishness is wrong because it is a noun and refers to lack of wisdom rather than an active habit of talking a lot. Graceful is wrong because it relates to elegance and physical poise, not to verbal output or conversation. Entertainer is wrong because it is a noun naming a profession or role and does not indicate that a person simply talks a lot.

Common Pitfalls:
Some learners may be tempted by entertainer because they associate people who entertain with talking or joking. However, the word loquacious focuses on quantity of speech rather than occupation. Another common mistake is ignoring part of speech and choosing a noun to match an adjective. When facing synonym questions, always check that the grammatical role of the option matches that of the target word, and then confirm the meaning by thinking of example sentences you might read in an article or hear in conversation.

Final Answer:
The word that is similar in meaning to Loquacious is Talkative.
