Pronunciation: [ɐspˈɜːɹe͡ɪt] (IPA) 
The correct spelling of the word "Asperate" is a subject of debate, as it can be written as "aspirate" or "asperate." The reason for this is due to the pronunciation of the word, which is /ˈæspəreɪt/ in IPA phonetic transcription. Some argue that the "h" sound in "aspire" is not present in the way the word is spoken, and therefore "asperate" should be used. However, "aspirate" remains the more commonly accepted spelling.
Asperate is a verb that refers to the act of making rough or harsh, either in terms of physical texture or sound. This word is often used to describe a surface or an object that has become jagged, uneven, or rough due to wear, erosion, or some other type of damage or abrasion. For example, if a sculpture made of marble had been exposed to harsh weather conditions for a long time, its smooth surface might become asperated and lose its original polished quality, resulting in a rough, uneven appearance.
In addition to describing physical roughness, asperate can also be used to describe sounds that are harsh, grating, or hoarse. For instance, the way a person's voice sounds when they have a sore throat or when they are shouting or screaming can be described as asperated. Similarly, certain musical instruments, like a badly tuned guitar, can produce an asperated sound that lacks the desired harmonious and smooth tone.
Overall, asperate is a versatile term used to convey a sense of roughness, harshness, or unevenness. Whether applied to physical surfaces or sounds, its use reflects the idea of something being abrasive, jagged, or lacking the desired smoothness and finesse.
To make rough or uneven.
