Pro Tip
Avoiding 'unkindly' as an adjective
In English, 'unkindly' is primarily an adverb (e.g., 'She spoke unkindly to him'). When describing a person or their behavior, use 'unkind' as the adjective (e.g., 'His unkind words hurt her feelings').
Gold Rule
Unkind vs. Cruel
'Unkind' implies a lack of kindness or thoughtfulness, while 'cruel' suggests deliberate harm or suffering. For example, 'She was unkind to ignore his question' suggests carelessness, whereas 'She was cruel to spread rumors about him' implies malice.
Word Origin
From Middle English 'unkynde', from Old English 'uncynde' ('unnatural, unkind'), combining 'un-' (prefix meaning 'not') and 'cynde' ('natural, kind'). The sense evolved from 'unnatural' to 'lacking in kindness' by the 14th century.
Usage Notes
Unkind is a general term describing behavior that is inconsiderate or causes emotional harm. It is milder than 'cruel' but stronger than 'rude.' It can describe both intentional and unintentional actions. In formal writing, 'unkind' is preferred over 'unkindly' as an adjective (e.g., 'an unkind remark' vs. *'an unkindly remark').
