The word "unraveling" refers to the process of undoing, unraveling, or disentangling something that is complicated or difficult to understand. The most immediate antonym of unraveling would be "assembling" that suggests the opposite of breaking down an item or a situation, by bringing together disparate pieces to create a cohesive whole. Another antonym that closely relates to the concept of unraveling would be "resolving" which implies finding a solution or an answer to a problem. Conversely, "complicating" would be an antonym with a negative connotation as it infers adding more layers of difficulty and confusion to an already complex situation.
