Definition of throw open

The phrase "throw open" is a figurative expression, first appeared in the English language during the 17th century. It originated from the literal meaning of "open" as a verb, which denotes the action of making something accessible or ajar. In the past, large doors were typically closed and fastened with heavy bolts or bars to keep out intruders. To "throw open" such doors meant forcefully pushing them aside or removing the barriers completely, making them swing wide open. This action symbolized a sudden and aggressive gesture of welcoming, granting access to others or returning something to an open state. The expression has since taken a more widely used metaphorical meaning, describing the manner in which an opportunity, idea, or possibility is made available or accessible in a decisive or abrupt manner. It conveys an impression of contrast, emphasizing the sudden and dramatic transformation of that which was previously closed or shut down into something more open and accessible to others. In summary, the origin of "throw open" is rooted in the notion of overcoming physical barriers to gain access, but its modern connotation signifies a metaphorical act of making something accessible or unconstrained through an act of forceful gesture or decisive action.
