The meaning of the word 'irascible' is characterized by a tendency to be easily angered and irritable. This term describes someone who has a quick temper or is prone to frequent outbursts of anger. In the context of mood and personality, 'irascible' paints a picture of someone who may not necessarily be joyful or calm, but instead is quick to respond with irritation or anger.

In comparison, the other options represent traits that are opposite or unrelated to being irascible. For instance, joyful and cheerful suggest a positive and happy demeanor, while calm and peaceful indicate steadiness and tranquility. Gentle and kind further imply a nurturing and mild temperament, which contrasts sharply with the notion of being easily angered. Thus, the correct choice highlights the defining characteristic of the word 'irascible.'
