Which word indicates something that is intricate or complicated?

The word "convoluted" is often used to describe something that is very intricate, complicated, or difficult to understand. It conveys a sense of complexity that requires careful thought to unravel or comprehend, making it particularly fitting in contexts where something is layered, twisted, or not straightforward. This could apply to a variety of scenarios, such as convoluted reasoning in a complex argument or convoluted plot lines in storytelling. The intricate nature of something described as convoluted suggests that it may not be easily navigable without significant effort or analysis.

In contrast, the other options do not encapsulate this sense of complexity. A covenant typically refers to an agreement or contract, which does not imply intricacy. Covert describes something hidden or secretive, focusing on concealment rather than complexity. Compliant refers to being obedient or agreeable, which also lacks the nuance of being complicated. Each of these words carries its distinct meaning, but none align with the intricacy that "convoluted" portrays.
