There is a web demo system called ICTCLAS (Institute of Computing Technology, Chinese Lexical Analysis System). It was developed by the Institute of Computing Technology, Chinese Academy of Science.
There is also a web demo system from THULAS (Tsinghua University - Lexical Analyzer for Chinese), which was developed by the Nature Language Processing Group, Tsinghua University.
NOTE: I don't know (and I cannot test) whether these site can be accessed freely across the world.
just write the word on google, then type definition after example: run definition Then a big box with the definition will appear, usually the first one shows what part of speech it is
There are many lexical analyzers for Chinese, but these are not developed for daily use, the typical usage is Chinese searcher engine.
I found 语言云 has a online demo, I test it by enter a sentence from today news,
The default result seems complicate, I deselected "语义依存分析" and "语义角色标注".
These tool can not be 100% accurate, for example, "选举" in the sentence is a noun, not verb ( so the SBV relation is also wrong, SBV means subject-verb), the biggest mistake is it split 因凡蒂诺(Sorry, Mr.Infantino) to 因 and 凡蒂诺.
These errors are understandable, it is still helpful.
