The concept of "illicit loves" refers to relationships that are considered inappropriate or forbidden. Antonyms for this phrase would be relationships that are acceptable or approved. Such relationships would include those that are socially acceptable, legally valid, and morally right. In particular, such relationships would include marriages, long-term committed partnerships, and relationships between consenting adults. These types of relationships are often based on trust, common values, mutual love, and respect. Unlike illicit loves, these relationships are celebrated, supported, and encouraged by society, and are often recognized and protected by laws and customs.
