What does folding mean?
Folding is the act of bending a flexible material—paper, cloth, metal sheeting, dough—so that one part lies over another, reducing its size or changing its shape without cutting or tearing. In everyday life it describes a familiar domestic routine: the folding of laundry, letters, and maps. It also works attributively to name a whole family of space-saving designs, from folding chairs and tables to folding bicycles and doors, where hinged construction lets an object flatten or collapse when not in use. Beyond the household, folding carries precise technical meanings: geologists speak of the folding of rock strata under tectonic pressure, and molecular biologists study protein folding, the process by which a chain of amino acids assumes its functional three-dimensional shape. The word connotes orderliness and economy—turning the bulky into the compact—and its ubiquity makes it useful across registers, from casual conversation to laboratory reports.
The action or an act of bending something flexible over on itself.
"The neat folding of the napkins impressed the caterer."
Present participle of fold: to bend something over on itself.
"She was folding the letters before sealing the envelopes."
(Attributive) Designed to be folded up or hinged for compactness or portability.

Rare in everyday English; 'foldings' appears mainly in technical contexts such as geology or mathematics to refer to multiple instances or structures of folding.
"The map showed the complex foldings of the Alpine rock strata."
Proteins do it, maps do it, and origami artists turn a single sheet into a thousand shapes — folding may be nature's favorite way to pack more into less.

Etymology of folding
Folding derives from the Old English verb 'foldan', meaning to bend or double over, which shares a common Germanic root with Old High German 'faldan' and related West Germanic forms. The noun and participial uses developed naturally from the verb in Middle English. The Germanic root also produced the combining element '-fold' (as in twofold, manifold), which expresses multiplication or repetition.
How folding is actually used
As an attributive modifier ('folding chair', 'folding door'), 'folding' describes something designed to collapse or hinge for compactness; this commercial/everyday use is extremely common. In scientific writing, 'folding' most often appears in 'protein folding', where it is neutral and technical rather than domestic.
Easily confused with folding
Fondling means caressing or touching affectionately (or inappropriately), while folding refers to bending material over on itself; the words merely resemble each other in sound.
