- spent (adj.)
- "consumed," mid-15c., past participle adjective from spend. Of time, "passed, over," from 1520s; as "worn out, exhausted from overwork," 1560s.
中文解释
1、以end结尾的不规则动词，其过去式和过去分词为将end变成ent，也就是将末尾的d变成t，d、t是一对对应的清辅音和浊辅音。2、反之，如果我们看到以ent结尾的动词，同时又非原形动词的话，我们首先应将其还原成end后看是否认识。3、实例单词：bend、lend、rend、send、spend、unbend、misspend.
