Letting one go typically refers to releasing or setting free, but its antonyms suggest opposite meanings. Holding on to someone or something, for instance, is the opposite of letting one go. Clinging, grasping, and gripping are other antonyms that denote the act of keeping or holding tightly. Conversely, detaining, trapping, and arresting imply preventing someone from leaving or escaping. In some contexts, the antonym could be interpreted as the opposite of forgiveness, like holding a grudge or seeking revenge. Nonetheless, antonyms for letting one go are numerous and vary depending on the context in which the phrase is used.
