than是什么意思

conj. 比, 除...外
prep. 比

conj. A particle expressing comparison, used after certain
adjectives and adverbs which express comparison or diversity, as more,
better, other, otherwise, and the like. It is usually followed by the
object compared in the nominative case. Sometimes, however, the object
compared is placed in the objective case, and than is then considered
by some grammarians as a preposition. Sometimes the object is expressed
in a sentence, usually introduced by that; as, I would rather suffer
than that you should want.
adv. Then. See Then.
