Linebreeding is a term often used to describe the milder, less intense forms of inbreeding. Linebreeding is also used though seldomly to describe breeding to an individual animal in a straight line like a dog bred to his own daughters for several generations, or a bitch to her sons for several generations.
What ever terminology you use, inbreeding is the breeding of related individuals.

Mmmm, I agree with what you said, but disagree with that one highlighted part. Several generations of father/daughter (or mother/son) would form the most intensive inbreeding you could get IMO.
