Common Mistakes

The teacher told him stern
The teacher told him sternly.
'stern' is an adjective; the adverb 'sternly' is required after a verb.
He sternly explained the rules, but gently.
He sternly explained the rules, then spoke gently.
'sternly' and 'gently' express opposite tones and cannot modify the same verb simultaneously.

Synonym discussion

Sense: adverb/1

All four adverbs describe firm or critical behaviour, but they differ in tone and context. Sternly conveys seriousness and disapproval without necessarily implying punishment — a parent can speak sternly to a child without being cruel. Severely is stronger, suggesting real hardship or strict consequences ('severely punished'). Strictly focuses on rule-following and precision ('strictly follow the instructions'), and can be neutral or positive. Harshly carries a negative edge, implying unnecessary roughness or lack of kindness ('harshly criticised'). If a teacher says 'Stop talking' sternly, students feel the teacher is serious. If the same words are said harshly, students may feel hurt or unfairly treated.

Etymology

Old EnglishMiddle EnglishEnglish

Sternly is the adverb form of stern, which comes from Old English styrne, meaning 'severe, strict, hard.' It is related to an Old High German word for 'stiff' or 'strong.' The adverb form has been used since at least the 1400s to describe the manner in which someone speaks or acts with firm seriousness.
