Etymology
From Middle English seryows, from Old French serieux, from Medieval Latin sēriōsus, an extension of Latin sērius (“grave, earnest, serious”), possibly ultimately from Proto-Indo-European *swer- (“heavy”). (If this root is correct, cognate with German schwer (“heavy, difficult, severe”), Old English swǣr (“heavy, grave, grievous”). More at swear, sweer. However, see sērius for an alternative derivation of the Latin.)
Webster’s 1913
- adjective Grave in manner or disposition; earnest; thoughtful; solemn; not light, gay, or volatile.
- adjective Really intending what is said; being in earnest; not jesting or deceiving. Beaconsfield.
