Morphology

tackifier = tackify (transparent) = tack + ify + er

Formed regularly from the verb 'tackify' with the agentive '-er'; the technical verb meaning is predictable from 'tack'.

Etymology

Tackifier comes from tack (a short word for 'stickiness') plus the parts -ify ('to make') and -er ('a thing that does'), so it literally means 'something that makes sticky'. That's why a tackifier is added to glue to make it more sticky.
