The construction of “Known but to God”
What does "but" mean in this case and what other uses is this word used in the same context. I'm trying to explain what this word means but I can't think of any good common use examples with the same meaning.
The clearest word I can think of is "just"
Life is just/only a dream
Example sentences I did think of used "nothing":
I found nothing but junk at the store.
But is this the same meaning?
I found nothing, just junk, at the store?
