ख़ूबी (khoobii)

noun A feminine noun meaning a good quality, strength, or special merit that someone or something possesses; also used to praise a distinctive feature.
Sense 1 : good quality, virtue, strength (of a person or thing)
noun, feminine
Synonyms: गुण (gun), विशेषता (visheshtaa), खासियत (khaasiyat)
Frequency: high
Cultural Note: You'll hear this word a lot in everyday appraisal-talk -- praising a person's cooking, a gadget's features, or a friend's character. Saying यही तो उसकी ख़ूबी है (yahii to uskii khoobii hai, 'that's exactly his/her special quality') is a very natural way to highlight what makes someone stand out, often right before or after mentioning a flaw, since Hindi speakers love balancing ख़ूबी (khoobii) against खामी (khaamii, 'flaw') in the same breath.
Common Mistakes: 1) Learners sometimes use ख़ूबी (khoobii) as if it only meant 'beauty' because of its sound resemblance to ख़ूब (khoob, 'excellent') -- it actually means a positive trait or strength, not physical beauty. 2) It is almost always used in the plural when listing someone's merits, e.g. उसकी ख़ूबियाँ (uskii khoobiyaan, 'his/her good qualities'), even though the singular is grammatically fine for one specific trait.
