Pronunciation: [njˈuː stˈʌf] (IPA) 
The spelling of the word "knew stuff" may seem odd because of its silent "k". In IPA phonetic transcription, the word would be written as /njuː stʌf/. The "k" is silent because it appears before a "n" which, in this case, sounds like the "ng" in "sing". This makes the "k" unnecessary and it is therefore not pronounced. So next time you see the word "knew", remember that the "k" is often silent when it appears before an "n".
"Knew stuff" is an informal phrase that refers to possessing knowledge or being knowledgeable about a particular topic or range of subjects. It is derived from the verb "to know" and the noun "stuff," where "know" means to have information, understanding, or familiarity with something, and "stuff" refers to facts, information, or details.
The phrase often indicates a certain level of expertise or understanding beyond a basic knowledge level. When someone is said to "know stuff," it suggests that they possess a substantial amount of information or specialized knowledge in a particular field or area. It implies that the person is well-informed, experienced, or educated about the subject matter.
"Knew stuff" can be used in various contexts, such as in casual conversations, discussions, or when discussing someone's skills or competencies. It can be applied to any domain or field in which knowledge can be acquired, including academic subjects, hobbies, or professions.
The phrase "knew stuff" can also be used ironically to indicate someone pretending to have knowledge or expertise they do not genuinely possess. It may be employed to describe someone who exaggerates their understanding or tries to impress others by claiming to know more than they actually do. Overall, "knew stuff" implies a level of knowledge and understanding that extends beyond a basic or superficial grasp of a subject.
The term "knew stuff" does not have a specific etymology on its own. However, if you are referring to the word "knew" and the term "stuff" separately, their origins are as follows:
1. "Knew":
- Origin: Old English ("cnawan")
- Etymology: From Proto-Germanic ("knewaną")
- Meaning: To be aware or familiar with something, to have information or knowledge about something.
2. "Stuff":
- Origin: Middle English ("stuf")
- Etymology: From Old English ("stūf")
- Meaning: Refers to a variety of things or materials that do not have a specific name.
Combining the two words "knew" and "stuff" does not create a new distinct word with a separate etymology.
