What's the difference in meaning between 'register' and 'registry'? Can both be used interchangeably when talking about an official (public) list of items, records?.
Output:
The online oxford dict says: Register noun official list or record, for example of births, marriages, and deaths, of shipping, or of historic places. a book or record of attendance, for example of students in a class or school or guests in a hotel. Registry: noun (plural registries) a place or office where registers or records are kept. But yeah, it also says that a registry too can mean a list. And I think 'Registry' is used more in the former context than the later. Even while talking in context of computers we say things like 'Windows Registry'. For me, the word register brings along a sense of being finite but registry does not. like when I think of a register of records, I usually get a quantified picture of the records list comes to my mind, like a page, or a notebook. but 'registry' brings along a picture of non quantifiable !! or its just weird with me. Anyone have other thoughts on this?
