Glue VS Adhesive

Just spelling and number of syllables. In common speech glue is more common. In professional literature adhesive is more common.

An old-dog of an engineer once told me the difference between 'glues' and 'adhesives'... as closely as I can remember it...

"NEVER bet Your life on a glued joint."

I wonder if those methods used to assess adhesive joint such as shear/ peel calculations and traction-separation for cohesive are applicable to glue joint also?
