Tam is used with adjectives, adverbs, and verbs, not nouns. Besides, the term "saint" only applies to texts that are from the Christian Era, so you shouldn't immediately assume it's "saint" if you do not know which text a passage is from (even if it is a Christian text).
Most men are rather stupid, and most of those who are not stupid are, consequently, rather vain. -A.E. Housman
