Definition of throw on

The origin of the phrase "throw on" dates back to the Old English language, specifically to the verb 'þrēan' meaning 'to throw'. This verb was used in various forms over time to indicate different types of actions. In the Middle English period, around the 15th century, the phrase "throwne" was used to mean "put on" or "put over", likely in reference to quickly putting on clothing or an item. This usage evolved over time, and today the phrase "throw on" is used primarily in American English to indicate a quick, casual, or impromptu action of putting something on, such as clothing, blankets, or chairs. The phrase can also be used in the past tense, as in "I threw on my coat before leaving the house." Here's a sentence to illustrate its use: The woman threw on a sweater as she ran out the door, not wanting to be caught without an extra layer on such a chilly day.
