Which word describes someone who is generally incompetent and ineffectual?

The term "feckless" is defined as lacking initiative or strength of character, which aligns closely with the notion of being generally incompetent and ineffectual. A feckless individual typically fails to take responsibility and is unable to produce effective results due to their lack of ability or motivation.

In contrast, "felicitous" refers to something that is well-suited or appropriate, often in terms of expressions or situations, which does not fit the description of incompetence. "Fracas" denotes a noisy disturbance or quarrel, which has no inherent connection to a person's capabilities or ineffectiveness. Lastly, "frieze" pertains to a decorative band on a wall, showing no relevance to the qualities that define someone as incompetent or ineffectual. Thus, "feckless" is indeed the most fitting choice for describing someone lacking competence and effectiveness.
