Pronunciation: [pˈi͡əsɪŋnəs] (IPA) 
The word "piercingness" is spelled with two "ss" at the end, despite the fact that the root word "piercing" only has one "s".

The "ss" ending is indicated by the voiced sibilant sound /z/ followed by the unvoiced sibilant sound /s/.
Piercingness is a noun that refers to the quality or state of being piercing. It is derived from the verb "pierce," which means to penetrate or make a hole in something by pushing a pointed object through it. In a figurative sense, piercingness describes something that is sharp, powerful, or intense, often in a way that evokes strong emotions or reactions.
When applied to a physical sensation, piercingness suggests a keen, acute, or overwhelming feeling. It may describe a sudden and intense pain or discomfort that seems to go through or penetrate a specific part of the body. For example, a piercingness in one's ear could indicate the sharp pain experienced after getting an earlobe pierced.
Piercingness can also describe a sound or voice that is shrill, loud, and penetrates through other noises, catching people's attention. It is often associated with high-pitched, clear, or cutting sounds that are capable of causing discomfort or annoyance. For instance, the piercingness of a fire alarm is designed to swiftly alert people to danger.
In a metaphorical context, piercingness can describe a person's gaze, words, or actions that are striking, incisive, or penetrating, capturing people's attention and leaving a lasting impact. It implies that these qualities cut through the superficial layers to reveal the truth or essence of a matter. A piercingness in someone's eyes might suggest their ability to see through deception or convey strong emotions and intentions.
