Etymology
- Old English (450–1100): Neither “serious” nor “seriously” existed in Old English. There is no Old English form of this word.
- Middle English (1100–1500): The word was still not part of English for most of this time. Its root is the Latin word serius, which means weighty, grave, and important. Near the very end of this period, in the late 1400s, “serious” reached English from Latin, perhaps through French.
- Modern English (1500–Present): English speakers formed “seriously” in the 1500s by adding the adverb ending -ly to “serious.” Over time it gained its degree sense (“seriously hurt”) and its truth-stressing use in daily speech.
