Interdigitation is a mouthful of a word that's often used in scientific circles to describe the method by which two objects like fingers or puzzle pieces interlock with each other. But if you're looking for a simpler word to describe interdigitation, you might try searching for synonyms like intertwine, mesh, interweave, or interlock. These words all capture the sense of two things becoming intertwined or interlocked with each other, but they do so in a more accessible and easier-to-read way than the more technical term "interdigitation." So whether you're writing an academic paper, a novel, or just trying to describe a tangled mess of wires, keep these synonyms in mind to make your writing clearer and more approachable.
