Confusion regarding the use of ‘threw’ and ‘through’ arises from the fact that they are homophones, ie, they are pronounced the same way. As a result, it is quite possible for one to be mistakenly used in place of the other. However, there is no similarity in their meanings:

• ‘Threw’ is the simple past tense of ‘throw’, when the latter is used as a verb.

  • meaning(s): to hurl or cast something from the hand or to project one’s voice. He threw the ball at the stumps, looking to run the batsman out.

• ‘Through’ is generally used as a preposition. Meaning, in brief:

  • to get into something from one end or side and come out the other. Example - The sunlight coming through the window woke me up.

  • to travel over or across or in something. Example - The plane hurtled through the air at supersonic speed.

  • to go past or beyond something. Example -The fugitives went through three red lights before the cops finally caught up with them.

  • to go from one to another of, or between or among individual members of something. Example -Tarzan swung through the trees like the forest was his natural habitat; The World Cup may have passed through many hands, but it is now India’s.
