The quality or state of being sticky, gluey, or tending to stick to other things.
From adhesive (Latin adhaerere, 'to stick to') + -ness (suffix forming abstract nouns). The -ness ending converts the adjective adhesive into a noun describing the property itself.
The adhesiveness of tree sap actually protects trees from insects and diseases—nature's original glue! This same principle helped scientists develop medical bandages and surgical adhesives that stick to skin without harming it.
