Understanding Irritable Disposition

The question asks us to find the most appropriate single word that describes someone who has an irritable disposition. An "irritable disposition" refers to a person's tendency or nature to be easily annoyed, upset, or angered. Such a person often displays a bad temper or mood.

Analyzing the Options

Let's look at the meaning of each given word option to determine which one best fits the description of "having an irritable disposition".

• Prudent: This word means acting with or showing care and thought for the future. A prudent person is wise and cautious. This does not relate to being easily annoyed or bad-tempered.
• Peevish: This word means easily irritated, especially by unimportant things. A peevish person is typically fretful and querulous. This meaning strongly matches the description of "having an irritable disposition".
• Pestering: This word refers to the act of bothering or annoying someone persistently, especially with frequent requests or interruptions. While related to annoyance, "pestering" describes an action (bothering others), not an inherent disposition or nature of being easily annoyed oneself.
• Palpable: This word means capable of being touched or felt; tangible. It can also mean so intense as to be almost touched or felt, like "palpable tension". This word is about something being perceivable or tangible, not about a person's temper or mood.

Identifying the Most Appropriate Word

Comparing the meanings, the word that most accurately describes someone "having an irritable disposition" is Peevish.

A person with an irritable disposition is someone who is naturally prone to being easily vexed or annoyed. The definition of peevish perfectly aligns with this tendency to be easily irritated, especially over minor issues.
