nog

The word "nog" has a curious split identity, with one path leading to holiday drinks and the other to old building work. Most modern readers meet it in eggnog, the festive drink made with eggs, milk or cream, sugar, and warm spices such as nutmeg. By itself, however, "nog" is not usually the everyday name for the drink. Instead, it survives mainly inside the larger word eggnog.

Older uses give the word more substance. In construction, a "nog" is a small wooden peg, block, or brace set between timbers or studs. It helps hold parts together, adds support, or gives a firm place for fixing other materials. Related forms such as nogging are used for this kind of structural work.

There is also an older drinking sense: in historical English, "nog" could mean a strong ale. This has led to one theory that eggnog grew from a mix of eggs and that ale. Another theory connects the name with noggin, a small wooden cup. Because the evidence is not fully settled, it is safest to treat these as likely explanations rather than proven fact. So "nog" is a small word with an unusual history: part of a famous holiday drink, a term from older brewing, and a practical name for a piece of wood that helps a structure stay firm.
