when your teacher asks a question, there is only one correct answer.But there is one question that has
millions of current answers.That
question is “What’s your name?” Everyone gives a different answer, but everyone
is correct.
Have
you ever wondered about people’s names? Where do they come from? What do they
mean?
People’s
first names, or given names, are chosen by their parents.Sometimes the name of a grandparent or
other member of the family is used.Some parents choose the name of a well-known person.A boy could be named George Washington
Smith; a girl could be named Helen Keller Jones.
Some
people give their children names that mean good things.Clara means
“bright”; Beatrice means “one who gives happiness”; Donald means
“world ruler”; Leonard means “as brave as a lion”.
The
earliest last names, or surnames, were taken from place names.A family with the name Brook or
Brooks probably lived near a brook;someone who was called Longstreet probably lived on a long,
paved road.The
Greenwood family lived in or near a leafy forest.
Other
early surnames came from people’s occupations.The most common occupational name is Smith, which means a person
who makes things with iron or other metals.In the past, smiths were very important workers in every town and
village.Some other
occupational names are: Carter — a person who owned or drove a cart; Potter
— a person who made pots and pans.
The
ancestors of the Baker family probably baked bread for their neighbors in their
native village.The
Carpenter’s great-great-great-grandfather probably built houses and furniture.
Sometimes
people were known for the color of their hair or skin, or their size, or their
special abilities.When there
were two men who were named John in the same village, the John with the gray
hair probably became John Gray.Or the
John was very tall could call himself John Tallman.John Fish was probably an excellent
swimmer and John Lightfoot was probably a fast runner or a good dancer.
Some
family names were made by adding something to the father’s name.English-speaking people added–s
or–son.The
Johnsons are descendants of John; the Roberts family’s ancestor was
Robert.Irish and Scottish
people added Mac or Mc or O.Perhaps
all of the MacDonnells and the McDonnells and the O’Donnells are descendants of
the same Donnell.
