The phrase "whistle for" is typically pronounced /ˈwɪsl fər/. The spelling of this word can be broken down into two parts. "Whistle" is spelled with a "wh" at the beginning, representing the /w/ sound followed by the /ɪ/ sound represented by the "i". "For" is spelled with an "o" to represent the /ɔ/ sound and an "r" at the end to represent the /r/ sound. Together, "whistle for" means to produce a brief, shrill sound by blowing air through pursed lips to signal or get someone's attention.
The phrase "whistle for" is an idiomatic expression that means to hope or wait for something in vain, usually implying that the desired outcome or object is highly unlikely or impossible to obtain. It suggests that the person or entity expecting or wishing for the result will be disappointed or left empty-handed.
This idiomatic phrase is derived from the action of whistling as a way of calling someone or something. When someone is said to be "whistling for" something, it implies that they are attempting to attract or summon it by whistling, indicating their strong desire or need for it. However, since whistling is often used to call animals, and not particularly effective in summoning people or objects, the expression "whistle for" has come to connote a futile or fruitless endeavor.
For instance, if someone is waiting for a promotion that they believe is imminent but does not receive it, we might say they are "whistling for a promotion," indicating that their expectation was unrealistic and unfulfilled. Similarly, if a person is hoping to win an impossible bet or receive a favor from an unresponsive or uncooperative individual, it can be said that they are "whistling for" the desired outcome.
The phrase "whistle for" originates from the Middle English word "whistlen" which means "to make a high-pitched sound by blowing air through the lips or a small instrument". Whistling has long been used as a means of communication, signaling, or attracting attention.
The word "for" in this phrase simply denotes the purpose or intended recipient of the whistle. So, when someone says to "whistle for" something or someone, they are calling or summoning that particular thing or person using a whistle. Over time, this phrase has come to indicate a demand or expectation for something that may be difficult or impossible to obtain.
