Question

Is 'ancient grandfather' the same word as 'great-grand father'?
father>grand father>great-grand father(=ancient grandfather)??If not, 'ancient grandfather'=great-great-grandfather?

Answer

No. Ancient grandfather means very old grandfather, while great-grandfather means grandfather's father.

Answer

each "great" that is pre-pended adds 1 more generation exactly. If you are looking for a general term, I would use "ancestor" or "forebears". http://www.thefreedictionary.com/forebears. Ancient just means very old, but not related to the number of generations. You can say "my grandfather looks ancient", it would be considered a bit impolite to say it directly to him though lol.

Answer

If not, 'ancient grandfather'=great-great-grandfather?
