The phrase "have a whack" originates from British English and is colloquial in nature. It consists of two parts: "have" and "whack".
The word "have" is derived from the Old English word "habban", which has its roots in the Proto-Germanic language. It has been present in the English language for centuries and is commonly used to indicate possession, obligation, or experience.
On the other hand, "whack" is believed to be derived from the Scottish word "whhak", which means "a sharp blow or crack". It is also related to the Middle Dutch word "wacken" and the Old High German word "wackon", both of which mean "to strike" or "to beat".
When these two words are combined, the phrase "have a whack" is often used to mean "to have a try" or "to attempt something".
