great-great-grandson

The term is a compounding construction built upon the core Old English word 'son'. The prefix 'grand', from Latin grandis via French, was added to create 'grandson', meaning the son of one's child. To extend the lineage further, the native English adjective 'great', from Old English grēat, was adopted as a replicable prefix. Each iteration of 'great-' pushes the relationship back one more generation in a logical, additive manner. Thus, 'great-great-grandson' transparently denotes a male descendant two generations beyond one's grandson, systematically mapping genealogical distance through linguistic repetition.
