Question: I am looking for a list of all English words that are their own antonyms. Off the top of my head, I can only think of 'either', 'fast', 'to dust' and 'to lease', but there must be dozens more. Can you provide a link to a comprehensive list, if such exists? Also, what are such words most commonly called? I like the term 'Janus word' I once heard, but is that widely understood? Edited by popular demand to make it absolutely clear that this is not a community wiki poll.

Answer: I think you're referring to Auto-antonyms. They are not the same word but a homograph (a word of the same spelling) that is also an antonym. I guess, Janus word is also acceptable. There was a list on Wikipedia (List of Auto-antonyms in English), since moved to Wiktionary's Appendix of English contranyms.


Question: For example: A situation needs both Fact A and Fact B to be explained, but a person accepts Fact A and rejects Fact B, misconstruing the situation? Do you think this is just ignorance or deliberate _____?.

Answer: You can call it a bias. Depending on the person's reason for rejecting fact B, you can use the name of the specific type of bias. For example, if the person chooses fact A over fact B because he already believes in fact A, it's called a confirmation bias. The tendency to prefer certain facts can be called partiality. Edit: the relation between the person and the fact they are rejecting can be called denial, and if the person does this often, you can say they engage in denialism.


Question: What is the difference between oath, pledge & vow and where should each word be used? An example should suffice.

Answer:
To me, the nouns pledge and vow are closer in meaning, to the point of being synonyms. They mean 'a solemn promise' (this is NOAD's main definition for both). Oath, while close in meaning, typically has an additional sense of invoking the divine (e.g., an oath taken on the bible). A verb with close meaning to all three is to swear. In addition to this meaning of 'solemn promise', each of these three nouns has specific additional meanings. an oath maybe refer to a profanity or a swear word vows maybe have specific meaning of commiting oneself to a given life, e.g. marriage or monastic vows pledge has an additional legal meaning, synonymous to surety, bond or guarantee
