Using "though" with "or" [closed]

Either they were friends or lovers, it's always just the two of them.

Though friends or lovers, it's always just the two of them.

I was wondering if both sentences mean the same thing, or does each one mean a completely different thing, and which one is more suitable in this context.

Also I'd like to know more about the usage of "though" & words of the same "family".

Solution 1:

No, the two sentences do not have the same meaning. The first needs a couple of corrections, and I suggest They are either friends or lovers; it's always just the two of them. This would mean that they are always together on their own and I have deduced that they are either friends of lovers. The second would mean that they are always together on their own, and that this is unusual because they are friends or lovers.

Though and although usually indicate that two things are in some way contrary to one another. Though the light was not bright, there was enough to see by. (Negative then positive). Though I was sick I did not ring work to let them know. (Contrary as a sick person is expected to ring work).
