What does mechanical mean?
Mechanical most often means connected with machines, machinery, or the physical processes they perform. It also describes behavior that seems automatic, repetitive, or governed by fixed rules rather than thought or feeling. A mechanical response may sound cold or indifferent, while “mechanical engineering” refers to the applied study of forces, motion, and machine design. Mechanical can therefore be descriptive and neutral, as in “a mechanical keyboard,” or critical, as when it characterizes someone's manner as lifeless and unthinking. The term is used in both British and American English without a major regional difference. In a sentence, its meaning depends on what it modifies: describing a device points toward machines, whereas describing a person's conduct suggests automatism and emotional distance. Its technical history also makes the adjective useful beyond everyday speech: it ultimately comes from a Greek term meaning “of machines” and preserves that literal association even when the word is used figuratively.

Where does mechanical come from?
The word entered English during the early modern period through Latin, in which mechanicalus was derived from the Greek mēchanikos, meaning “of machines” or “skilled in machines.” Greek mēchanikos came from mēchanē, the source of related English words such as machine, mechanic, and mechanism. The original association with machinery is therefore still evident in the modern adjective.
