One element of success when writing/editing historical or children’s work is the use of language. It is very important to understand the language spoken during a specific time period or focused toward a particular age group. Words that were used as recently as 25 years ago may not be used today or have a different meaning than in the past. For example, the word balderdash was one of the worst curse words a person could use 150 years ago. It is rarely used today. Consider what the culture and society was like for the particular group you are writing about. Different cultures may have many words for the same thing. A medieval warrior might be a knight in England, a samurai in Japan, a Shaolin monk in parts of the Far East, or a Templar in Latvia and Lithuania. Merchants who were looked upon favorably in western culture were the lowest members of society in China.

An anachronism is an event, person, item, or verbal phrase placed in the wrong historical time period. Here is an example from Shakespeare’s Julius Caesar, in Act II, Scene I, lines 193-194.

Brutus: Peace! Count the clock.
Cassius: The clock has stricken three.

Of course the wall clock was invented by the Swiss hundreds of years after the Roman Empire’s collapse. Do your research before taking on the giant task of writing a historical work.
