In dialects where both obliged and obligated are used, there is no standard distinction drawn, though individuals may distinguish nuance or use idiosyncratically. In technical discussions, particularly legal ones such as The Concept of Law by H. L. A. Hart (1961), the words may carry different meanings, such as obligations inherent to a relationship versus ones externally imposed.
The "grateful or indebted" sense is considered dated in some contexts.
- (under obligation): obligated
