This could be a double definition.

'identifies' is the first definition.
Although both the answer and definition are verbs in their -s form, I don't see how one could define the other.

'pins' is the second definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe you can see an association between them that I don't see?

Can you help me to learn more?

(Other definitions for nails that I've seen before include "Filed regularly" , "measure of hardness?" , "Metal spikes" , "Fixing pins" , "Part of body; hard as them" .)
