also

The word "also" originates from Old English eallswā, a combination of eall (meaning "all") and swā (meaning "so" or "in this way"). Over time, it evolved into Middle English alswa and later simplified to "also." The morpheme al- preserves the sense of inclusiveness ("all"), while -so retains its adverbial function ("in this manner"). The word’s development reflects a logical progression from "entirely in this way" to its modern sense of "in addition" or "likewise."
