Calcify
Biological Process
 Remember 'calcify' often relates to natural physical changes within living organisms.

 Gradual Change
 'Calcify' can imply a slow transformation rather than an instant one.

 Not Always Total
 Calcification does not mean the entire tissue turns to bone; it's often partial.
