+ [3 t* w& L7 J+ R; r: ]classify —一个很多词典都阵亡的词[...]

主流词典，一般把 classify、classified 都作为单独条目。

classified 有“机密的、保密的”意思，很容易就想到，这个词应该是 classify 派生而来的，但是去查 classify ，你却会发现，有对应义项的英英词典，只是少数。

其他如 OALD、LDOCE、MWALED、CALD、COBUILD 等的 classify 条，都没有类似义项，甚至 OED2 也没有（或许这个义项其实源自美语？）。

感觉一个动词如果总是后面加ed作为形容词用，慢慢的，那个原来的动词词条就消失了，不单列了，特别是对比一个词典的老版和新版，这一点改变的比较多。
