Overfolding

Part of speech: verb

Definitions

1. The action or process of folding something excessively or beyond its typical limits, often resulting in multiple layers or a thickened appearance; in science, it may describe the superposition of structures or data beyond normal overlap
2. The act of creating folds in an object or material more than necessary, producing complex creases or convolutions; it can also refer to the occurrence of additional folds in geological layers or mathematical data manipulations
3. Describing the process where folding is applied to something to an exaggerated degree, causing intricate layering or overlapping; this term is sometimes used to characterize overcomplicated patterns in textiles, biological formations, or algorithmic handling of information

Etymology: "Overfolding" is the present participle and gerund of "overfold", a compound built from the prefix "over-" and the verb "fold". The base sense is simple enough: "over-" adds the idea of excess, so overfolding is folding beyond what the job requires, leaving tight, tangled creases in fabric, paper or similar material. The more specialised sense comes from geology. In that field the word translates German "Überfaltung", where rock strata are bent and folded over on themselves, sometimes so far that the upper layers lie inverted across the lower ones. Geologists borrowed the idea and the German term, and the English usage carried the same notion of layers pushed past their normal arrangement. The mathematical and data-handling uses extend the figure further, describing repeated or excessive folding operations applied to a set of values. Each of these senses rests on the same picture of material doubled back on itself more than once.
