The Origin of Through or Threw

Although through and threw sound alike, they come from different Old English words and developed different meanings over hundreds of years.

Origin of Through

The word through comes from the Old English word þurh (thurh), which meant from one side to another, across, or by means of. Over time, its spelling changed while its meaning stayed almost the same.

Today, through can work as:

A preposition
An adverb
An adjective

Examples:

Origin of Threw

The word threw comes from the Old English verb þrāwan, which meant to twist, turn, or throw. As English evolved, throw became the base verb, and threw became its simple past tense.

Examples:

She threw the keys onto the table.
The player threw the ball across the field.

Why Do They Sound the Same?

English pronunciation has changed much faster than spelling. As a result, many words now sound alike even though they have different spellings and meanings. These are called homophones.
