Weathervane

A weathervane has four steady arms. Each arm bears a letter telling in which direction in points, E, S, W, or N.

Above the four arms is an arrow that turn about with the wind. When the west wind blows it turns the arrow round so that its point points to the west. When an east wind blows round goes to the east. The "point" of the arrow always points to whatever wind is blowing. If you look at the arms you can tell in what direction the arrow points. If it points somewhere between the north arm and the west arm, a north-west wind is blowing.

Sometimes a weathervane has a cock on it instead of an arrow. It is then called a weathercock. The beak of the cock always points to the wind that is blowing, and we can tell the name of the wind by looking at the arms. If the beak points in the same direction as the N-arm, a north wind is blowing.

It's the rule for root words ending in "c" is that you have to add “k”, so the spelling is related with the pronunciation. If we don't add the <k>, it looks as if the <c> has to be pronounced /s/. If the "k" was not there, “panicing” would look like the word which is supposed to be pronounced as if it is ended in "sing," while “paniced” would be pronounced like “panised”.

The same would …

Petticoats, breeches and Pinafore

One of the milestones that a little boy passed at the age of four or five was the transition from baby clothes or petticoats to trouser or breeches. He would still wear a pinafore to protect his clothes, but he was expected to be able to dress himself and tie the strings of his pinafore in a bow, at the back.
