불만족스럽다

Both relate to dissatisfaction, but they're used a little differently. 불만족스럽다 describes something that is unsatisfactory or doesn't meet expectations. It's more about the quality or state of an object or situation. For example, '이 서비스는 불만족스러워요' (This service is unsatisfactory). 불만이다, on the other hand, means 'to be dissatisfied' or 'to have a complaint.' It often implies a feeling or a direct complaint from a person. For instance, '저는 그 결과에 불만이에요' (I am dissatisfied with that result).

It's generally not used to describe a person directly in a negative way like 'this person is unsatisfactory.' You might use it to describe a person's performance or work as unsatisfactory, but not the person themselves. For example, '그의 작업은 불만족스러웠다' (His work was unsatisfactory).

You'd often use it when something doesn't meet your expectations or standards. Think about when you'd say something is 'disappointing' or 'not up to par' in English. This could be about a product you bought, a service you received, a performance, or even results from an effort. For example, '음식의 맛이 불만족스러웠어요' (The taste of the food was unsatisfactory).

You can soften it by using expressions like '조금 불만족스러워요' (It's a bit unsatisfactory) or by using honorifics if applicable, though the word itself is quite direct. Sometimes, it's more polite to express your dissatisfaction indirectly, for example, by saying '개선이 필요할 것 같아요' (I think improvement is needed) instead of directly calling something unsatisfactory.

The opposite is 만족스럽다 (manjokseureopda), which means 'to be satisfactory' or 'to give satisfaction.' For example, '그 결과는 매우 만족스러웠다' (The result was very satisfactory).

Yes, it does! Like other descriptive verbs (adjectives), you add -았/었-. So, it becomes 불만족스러웠다 (bulmanjokseureowotda) in the past tense. For example, '어제 본 영화는 불만족스러웠어요' (The movie I watched yesterday was unsatisfactory).

Absolutely! You can use adverbs like 매우 (mae-u, very), 아주 (a-ju, very), 정말 (jeong-mal, really), or 조금 (jo-geum, a little). For instance, '서비스가 매우 불만족스러웠어요' (The service was very unsatisfactory) or '결과가 조금 불만족스러웠어요' (The result was a little unsatisfactory).

It's generally a neutral to slightly formal word, suitable for most situations. You can use it in both formal and informal contexts by adjusting the ending of the sentence (e.g., -어요/-아요 for polite informal, -습니다/-ㅂ니다 for formal).

Break it down: 불- is a negative prefix (like 'un-' or 'dis-'). 만족 (manjok) means 'satisfaction.' And -스럽다 (seureopda) is a suffix meaning 'to be like' or 'to have the quality of.' So, it literally means 'to be like dissatisfaction' or 'to have the quality of being unsatisfactory.' Thinking of these parts can help you remember the meaning.

Yes, you can. If the food doesn't taste good, isn't prepared well, or doesn't meet your expectations, you can say it's 불만족스럽다. For example, '이 레스토랑의 음식은 항상 불만족스럽다' (The food at this restaurant is always unsatisfactory).
