What does foulest mean?
Foulest is the superlative form of foul, an adjective meaning extremely unpleasant, offensive, or objectionable. In everyday use, it most often identifies the worst example of something: the foulest smell, the foulest lie, or the foulest decision among several equally bad options. Its force comes from combining the idea of extreme unpleasantness with the added emphasis of a superlative, making it stronger than simply saying very foul or extremely bad. The word can refer to physical qualities such as smell, dirt, or weather, but it is also widely used for immoral, unfair, or deeply objectionable behavior. Although foulest is primarily an adjective, it can function adverbially in older, literary, or deliberately emphatic styles. It is understood throughout British and American English and is especially useful when the comparison is explicit.
The superlative of foul: more foul than all others in a particular comparison, especially in terms of smell, conduct, morality, or inappropriateness.
"He delivered the foulest insult during the entire argument."
This is the usual modern use. It may also be used substantivally in phrases such as the foulest, although that construction is less common.
In the foulest manner or to the greatest degree of foulness.
"The water tasted foulest once the heat began."
This use is uncommon in contemporary English and can sound literary, archaic, or intentionally emphatic.
When one thing is the ultimate example of bad, foulest is the word that says it has reached the absolute bottom.
