What does decalcified mean?
Decalcified means freed of calcium deposits or of the mineral component that makes bone hard. In anatomy and histology, the term usually describes bone or tissue that has been treated to remove its calcium salts, leaving an organic matrix that is easier to cut, section, or examine under a microscope. The word can also function as a past-tense verb form: a sample is decalcified before processing. Decalcification differs from simple erosion or cleaning; it specifically removes or reduces calcium-based mineralization. As a result, decalcified material is often softer and more fragile, an important laboratory consideration. The term is technical rather than literary, but it is useful because it distinguishes a deliberate removal of mineral deposits from ordinary wear, dissolution, or a natural loss of minerals. In medicine, dentistry, paleontology, and materials science, it names a clear technical process and its result.
Having had calcium or lime deposits removed, especially from bone or another calcified tissue.
"The decalcified skeleton revealed fine details of its internal structure."
Usually describes the result of a deliberate treatment in a laboratory, medical, or archaeological context.
To remove calcium or lime deposits from a substance, especially bone or tissue.
"The technician decalcified the specimens before sectioning them."
Less common than the participial adjective; the passive form is especially frequent in technical writing.
Decalcified bone keeps its collagen scaffold while surrendering its calcium, revealing the biological architecture that mineral normally conceals.

Etymology of decalcified
The word belongs to the English verb decalcify, formed from the prefix de- and the Latin-derived verb calcify. Calcify comes through Latin calcificare, associated with calx, the Latin word for lime or chalk. English later extended the formation to the resulting state and to the process of removing calcium deposits.
