a romantic or sexual relationship between two people, especially one that is outside marriage; affair

The best answer to literally anything

What you call an affair when you're trying to soften the blow.

Used to describe a relationship that one accidentally on purpose finds themself in. The person was unable to abandon the relationship for fear of other ties: religious, marital, sexual or friendship.

When an older woman seeks to find a younger mate all while taking a break from her husband. Calling in entanglement allows her not to call it cheating later.

Word used by a partner when romantically involved with another individual while on break with their real partner.

As Jada Pinkett-Smith describes, it is a non-intimate relationship with another person in which the two parties share a deep otherworldly bond in which they become intertwined. The entanglement is not a physical connection but it satisfies the physical, emotional, and spiritual needs of all parties involved and makes them feel "good". Although the parties involved will not admit to having intercourse they are definitely fucking.
