The word "pestilential" is spelled with a "t" and not a "c" in the middle. The sound made by the "t" is the voiceless alveolar plosive /t/, which is pronounced by pushing air through the mouth and abruptly stopping it with the tongue touching the alveolar ridge. This sound is different from the voiceless alveolar fricative /s/ made by the letter "c". The word means causing a deadly epidemic disease or poisonous or harmful, and is often used to describe something or someone that spreads a dangerous influence.
Pestilential is an adjective that describes something or someone causing or capable of causing a deadly or contagious disease, or being extremely harmful or dangerous. The term is often used in reference to a widespread epidemic or a highly infectious disease that affects a large number of people, animals, or plants.
In terms of a physical disease, pestilential can describe an affliction that spreads rapidly and poses a significant threat to public health. This could involve the rapid transmission of bacteria or viruses, resulting in severe illness, high mortality rates, or devastating consequences for an affected population.
The term can also be used metaphorically to denote something or someone that is highly destructive, harmful, or toxic. For example, a pestilential ideology or belief system can be one that spreads rapidly, causing emotional, psychological, or even societal damage, like radical ideologies or extremist views.
Additionally, pestilential can describe an offensive smell or odor that is extremely unpleasant, foul, or noxious. This usage refers to foul odors that are reminiscent of decay, rot, or disease.
Overall, pestilential encompasses the ideas of contagion, harm, danger, and destruction, both in a literal and metaphorical sense.

The word "pestilential" comes from the Latin word "pestilentia", which itself is derived from the Latin word "pestis", meaning "plague" or "epidemic". The term "pestis" originally referred specifically to contagious diseases that cause widespread harm and death within a population. Over time, the word "pestilential" has come to describe anything that is harmful, destructive, or pernicious.
