Some compound words (like bus rapid transit, dog whistle, or identity theft) don’t appear on the drop-down list when you enter them into the search window. If a compound term doesn’t appear in the drop-down list, try entering the term into the search window and then hit the search button (instead of the “enter” key). Alternatively, begin searches for compound terms with a quotation mark.

[Latin sevērus, serious, strict; see segh- in the Appendix of Indo-European roots.]

se·verely adv.
se·vereness n.

Synonyms: severe, stern1, austere, ascetic, strict
These adjectives mean unsparing and exacting with respect to discipline or control. Severe implies adherence to rigorous standards or high principles and often suggests harshness: "Praise or blame has but a momentary effect on the man whose love of beauty in the abstract makes him a severe critic on his own works" (John Keats).
Stern suggests unyielding disposition, uncompromising resolution, or forbidding appearance or nature: "She was a stern woman who ran the household with precision and an iron hand" (Margaret Truman).
Austere connotes aloofness or lack of feeling or sympathy, and often rigid morality: "The captain ... was an austere man that never laughed or smiled that one could see" (Alan Paton).
Ascetic suggests self-discipline and often renunciation of worldly pleasures for spiritual improvement: "Be systematically ascetic ... do ... something for no other reason than that you would rather not do it" (William James).
Strict means requiring or showing stringent observance of obligations, rules, or standards: "She was afraid to wake him up because even in his sleep he seemed to be such a strict man" (Eudora Welty).
