MEANING: noun: A grandfather’s father: great-grandfather.

ETYMOLOGY: From Old French besayel/besaiol, from Latin bis (twice) + avolus, diminutive of avus (grandfather). Earliest documented use: 1480.

NOTES: A grandfather is an aiel, a great-grandfather a besaiel, a great-great-grandfather a tresaiel. Now that you know the pattern, feel free to coin words beyond your grandfather’s grandfather. Also, now that you know what to call them, who’s your besaiel?

BESOIEL - to bedeck with silk

BESAIL - a second attack, coming right after you ASSAIL

B.S. AIEL - You say "aiel" is "Grandfather"? That's bullsh*t.
