The word "ruler" comes from the Old French word "ruler" which means to rule or govern. It was first recorded in the English language in the 14th century.
Examples:
"I need a ruler to measure the length of this piece of wood." (我需要一个尺子来测量这块木头的长度。)
"She always keeps a ruler in her pencil case." (她总是在铅笔盒里放着一个尺子。)
"He used a ruler to draw a straight line on the paper." (他用尺子在纸上画了一条直线。)
