tatarabuelo

Coined by analogy with tataranieto, and this of tratranieto, of the prefix tras- reduplicated and nieto; formerly trasabuelo was the usual term for our modern bisabuelo. Coromines dates the term around 1625[1]

tatarabuelo m (plural tatarabuelos, feminine tatarabuela, feminine plural tatarabuelas)

1. great-great-grandfather (great-great-grandmother for the feminine form)
2. (usually in the plural) great-great-grandparent (either a great-great-grandmother or a great-great-grandfather)

The noun tatarabuelo is like most Spanish nouns with a human referent. The masculine forms are used when the referent is known to be male, a group of males, a group of mixed or unknown gender, or an individual of unknown or unspecified gender. The feminine forms are used if the referent is known to be female or a group of females.
