I just stumbled upon the three words 實驗
(shíyàn), 測驗
(cèyàn), and 試驗
(shìyàn). Looking them up on mdbg.net and on Google Translate, they all translate to "test/experiment". So I was wondering: what (if any) is the difference between them? Are they exact synonyms or is there a subtle difference in meaning?
PS I wss looking for word-usage but it doesn't exist. I'm not sure if there are better tags for this post. If you know any, feel free to edit.
