The English phrase 'great grandson' is translated into Spanish as bisnieto.

The word bisnieto is used to refer to the son of one's grandchild.

What does it mean word for word?

The term is formed with the prefix bis-, meaning 'twice' or 'two-fold', which indicates that the person is the second generation after a grandchild.

The plural form bisnietos is used when referring to a group of great-grandsons or a mixed-gender group of great-grandchildren.

/bisnjeto/

The word bisnieto shares the same Latin root as the English word 'bisect', which means to cut something into two parts.
While English adds 'great' to indicate further generations, Spanish uses the prefix bis- for great-grandchildren and tatar- for great-great-grandchildren, such as tataranieto.
While bisnieto is the standard term, some traditional families use chozno to refer to a great-great-great-grandchild, moving beyond the standard prefix system.
