alcoholically comes from alcoholic + -ly; from alcohol, from Medieval Latin alcohol, from Arabic al-kuḥl ('the kohl, fine powder'), the term later extended to distilled spirits. Morphologically, the word is transparent: -ly is attached to the older base named in the history, so the modern form packages an inherited or borrowed stem inside a later English derivative. In modern use, the adverb sense is "in a manner relating to or affected by alcohol", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as alcohol, alcoholic, alcoholism, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Arabic al-kuḥl, which anchor the explanation in named linguistic material.
