## Definition

an old-fashioned name for a girl or a sweetheart. It was common hundreds of years ago but is rarely used this way today.

For teachers: a female sweetheart or girl. Historically used as a generic female counterpart to 'Jack'.

## Examples

- The old song tells of every Jack and his Gillian.
- In medieval ballads, the name Gillian often appeared to represent any young woman of the common people.
- The nursery rhyme 'Jack and Jill' is actually a later variation of the older pairing of Jack and Gillian, which served as a linguistic shorthand for an ordinary couple.

## Usage notes

- Often shortened to 'Jill' in modern contexts; the full form is now almost exclusively a proper name.
