1660s, from un- (1) not + conditional. Related: Unconditionally. Unconditional surrender in the military sense is attested from 1730; in U.S., often associated with Civil War Gen. Ulysses S. Grant and the taking of Fort Donelson. The ringing phrase of Grant's latest despatch circulated through the North like some coinage fresh from the mint, and Unconditional Surrender, which suited the initials of his modest signature, became like a baptismal name. [James Schouler, History of the United States of America, Dodd, Mead & Co., 1899].
Splitting Fingernails. Fingernails can crack and break because of several reasons. The most common factor being, nail-hardening products and nail polish that may be drying up the nails.

Finger nail splitting and hypothyroidism. Hello, I have been hypothyroid for over 20 years. Years ago I started to notice a problem with my left thumb which would keep splitting vertically. Over the years it has spread to about 5 of my fingers at different times. I have to keep nails shorter than I would like like but they still split. Just be chance the other day I read online that vertical splitting is caused by under active thyroid. Anyone have this same problem and have you found a solution. Thanks.
