unskillfully

This adverb carries a critical or negative connotation, emphasizing a failure to meet a professional or technical standard. It is often used to describe an outcome that was avoidable had the person possessed the proper training or experience. While "clumsily" refers to a lack of physical coordination, "unskillfully" specifically targets a lack of competence or mastery in a particular craft or discipline.

In professional or formal reports, this term is used to pinpoint a specific failure in execution. It suggests a gap between the required expertise for a task and the actual ability of the person performing it, often implying that the resulting error was a direct consequence of this deficiency.
