What does inefficiently mean?
Inefficiently means that something is done in a way that wastes time, effort, energy, or other resources, or that fails to produce the intended result. It is the adverb form of inefficient and is commonly used with verbs such as work, operate, run, use, and manage. For example, a company may describe a process as operating inefficiently when it duplicates work, delays responses, or uses more resources than necessary. The word is especially useful in professional, academic, and technical contexts, where it can identify measurable problems in performance, though it is also understood in ordinary conversation. Its meaning is broader than merely being slow: inefficiency can involve a task that is completed quickly but in a wasteful, disorganized, or ineffective manner. The related noun is inefficiency, while the opposite is efficiently.

Where does inefficiently come from?

Efficient ultimately comes from Latin efficere, “to bring out” or “accomplish,” built from ex-, meaning “out,” and facere, “to make.” The related words deficient, sufficient, and proficient belong to a broader Latin family based on forms of facere meaning “to make” or “to do.”
