My Cat's Philosophy

My cat is a philosopher. He is as terse as he is wise.

Every morning he says to me, "menow."

That's all he ever says.

Me Now.

He has summed up his philosophy is just two words.

Dunderhead

On the same page as dubious is another powerful word, dunderhead.

Dunderhead comes from a Scottish dialect and means a stupid person. It is unequivocal and unambiguous, not dubious at all, perfectly clear. What's the word for that? Perspicuous?

Yes! I like it.

Perspicuous means having clarity of expression or style; lucid. From Latin.

So a dunderhead would rarely be perspicuous, though the meaning of the word is always crystal clear.
