Wether

The bull, the cow and the calf are covered with hair. The ram, or wether, the ewe and the lamb have wool. The billy goat, the gelded goat, the she-goat and kid have long hair and beards.

A wether is a castrated male sheep or goat. A bellwether was originally a wether who led a flock of other sheep; a bell was placed around his neck to help locate the animals.

Although the male goat kids are often culled because they will never produce milk, they are sometimes castrated instead and allowed to remain in the herd as a "wether". With a bell around its neck, such a "bellwether" is usually the leader for the rest of the herd.

"Weather" and "whether" are homonyms; be careful not to confuse them while writing. And of course neither should be confused with their other homonym, "wether", which refers to a castrated male goat.

I wonder whether the wether will weather the weather or whether the weather the wether will kill.

Wether it is possible or not, I think I should ask him about his opinion

I am a tainted Weather of the flocke, / Meeteſt for death, the weakeſt kinde of fruite

There was a great fyer in the chamber, the wether was colde, and I saw now and then a Bishop come out;
