This sounds like a metal band who are proud of their common ancestry.
Or maybe a metal reggae band
what is meant by "nails and roots"?
Nails (as in the things you hit in with a hammer) and roots (parts of a plant) ... just that, no further context.
And I thought of the things you have on the fingers (or should you say 'fingernails' in good English?) anyway, your explanation isn't more logical :-)
Yeah, that would kind of make more sense, but no, they taught us the word for the metal things.
(And yeah, you can say 'fingernails' but when it's clear, just 'nails' is enough.)
Now they clarify this by adding "construction" to the translation
In what world do these go together?
“What do you have in your pockets?”
“Um, just nails and roots.”
