Is it acceptable to write alright as one word, rather than two separate ones? For example:
将all right 用单个单词alright来代替是不是可以接受的呢？比如：
She calls them whenever she is travelling to assure them she is alright.
事实上，alright是all right 的合并词。
Similar ‘merged’ words such as altogether and already have been accepted in standard English for a very long time, so there is no logical reason to object to the one-word form alright.
Nevertheless, many people dislike it and regard it as incorrect, so it’s best to avoid using alright in formal writing. Write it as two separate words instead:
如上面的例子可写为：She calls them whenever she is travelling to assure them she is all right.
