Pronunciation: [bjuːtˈɪɹɪk] (IPA) 
The word "butyric" is spelled with a "u" after the "t" because it comes from the root word "butyr" which means "butter" in Latin. The "y" in the root word became a "u" in English due to sound change over time. Therefore, "butyric" is pronounced /bjuːˈtɪrɪk/ with a "yoo" sound followed by "tir-ick". This word is often used to describe a pungent odor commonly found in cheeses and spoiled dairy products.
The term "butyric" refers to something that is related to or derived from butyric acid. Butyric acid is a short-chain fatty acid with four carbon atoms, known chemically as C4H8O2.

It occurs naturally in various animal fats and plant oils, and is notably present in several dairy products such as butter and Parmesan cheese.
In dictionary terms, "butyric" is used as an adjective to describe substances, compounds, or chemical characteristics associated with butyric acid. For example, a product or substance may be described as having a butyric smell or taste if it possesses a similar rancid odor or flavor reminiscent of butyric acid. Additionally, "butyric" could refer to anything that is produced, composed, or related to butyric acid in a chemical or biological context. This would include compounds or substances that contain butyric acid as a component or produce it as a byproduct.
In summary, the term "butyric" denotes anything linked to or derived from butyric acid, a short-chain fatty acid most commonly found in animal fats and dairy products. It is an adjective used to describe substances, characteristics, or compounds that exhibit the smell, taste, production, or composition associated with butyric acid.

The word "butyric" is derived from the Latin term "butyrum", meaning "butter". It is related to the Greek word "boutyron", which also means "butter". The connection between the word and its meaning comes from the fact that butyric acid, a compound responsible for distinct odors in rancid butter and human sweat, was first isolated from butter and is typically found in the fat of dairy products. Hence, the term "butyric" was adopted to describe compounds related to or derived from butyric acid.
