Dis-feature, which means the absence of a desirable feature, has a number of antonyms. Some of these include asset, advantage, perk, strength, benefit, and plus. These antonyms are all words that describe something positive or desirable about a person or thing. An asset is something that adds value, advantage is something that gives an edge over others, a perk is a bonus or benefit, strength is a positive attribute, benefit is an advantageous result, and plus is something added to improve the overall quality. Using these antonyms in place of dis-feature can provide a more positive, optimistic tone to communication.
