區別就是兩者意思是不一樣，具體的不同如下
they中文意思是pron. 他們它們她們
theyr中文意思是 weather products represent an innovative step for the yachtsman to gain a much more detailed insight than previously possible..
they 與 their的區別較爲明顯，對我們來說是較容易去區分的。
they是“他們”的意思，如 They are friendly and enthusiastic.
their是“他們的”的意思，如 Their books are all tidy.
