Chick
The word 'chick' was originally used to describe the young of any bird, especially the young of a baby chicken. One example of when this word was used to have the above meaning (in written discourse) is as follows; 'The courage which the hen exhibits when her chick is threatened with the foe.'
It was sometimes also used to describe a young (human) child. Example as follows; 'And so dresse him up with Love, As to be the Chick of Jove.'
Because of the connotations associated with a baby chicken (eg: small, cute etc), the word the picked up another meaning; a good looking girl. This meaning originated in the US and carried connotations of being good looking and innocent.
Now, the American meaning has stuck and is used with this connotation. From this, words like 'bird' have stemmed and have a similar meaning.
Bachelor
The word bachelor was originally used to describe a young knight (too young to be classed as a true knight). One example of when this has been used in an older text is as fllows; 'Yong, fressh, strong, and in Armes desirous, As any bachiler of al his hous.'
The word itself has changed in its spelling from examples such as 'Bacalar' and 'Baccalare' to the spelling we use today of 'Bachelor'.
The word has also changed in its meaning to the home of, or dwelling suited to, a single man. An example of when this word has been used in a contemporary text is as follows; 'Units range from 300-square-foot bachelor pads to 600-square-foot, one-bedroom suites.'
Witch
The word witch was originally used to describe a male who practices witchcraft. An example of when this word was used with this meaning is as follows; 'The examination of that grand Witch, Lewis Gaufredy, before noble Commissioners.'
The word then changed in meaning to be used to describe a woman who participates in the same practices. An example of where this has been used in text is as follows; 'I have heard of one old witch changing herself into a pigeon.' This example better reflects the semantics and spelling of the word that we would know today.
