Is "fallace" a word representative of "fallacy," or some variant spelling?

Question

Is there a form of the word fallacy as such: something along the lines of erroneous, or at fault, some version of the word fallacy without the 'y'. Otherwise what are some good suggestions that ring true to the word fallacy, as I feel erroneous is not quite the right word to use.

Answer 1

"Fallacious" is I think the word wanted

• Merriam-Webster gives the senses:

• 1 embodying a fallacy : a fallacious conclusion; a fallacious argument
• 2 tending to deceive or mislead : delusive false and fallacious hopes

• Cambridge gives:

not correct: His argument is based on fallacious reasoning.

It lists as synonyms:

• erroneous formal

• Collins states:

If an idea, argument, or reason is fallacious, it is wrong because it is based on a fallacy.
