Etymology

The word "murderous" combines "murder," derived from Old English morþor (meaning "secret killing" or "crime"), with the suffix "-ous," from Latin -osus (indicating "full of" or "having the quality of"). Over time, "murder" evolved in Middle English to its modern spelling, while "-ous" became a common suffix for forming adjectives. The fusion reflects a shift from literal killing to broader connotations of extreme violence or malice.
