La única cuerda
 

What does this mean?

¿ …. o era la única cuerda?

Could it be figuratively limited to a single musical note.

…. or was it the only string? Literal translation.
Context is needed.
It could be a way of saying or something else.:confused:

The only sane one?

The only sane one


Would fit in context


Something like
Are you crazy or am I the only sane one


I can’t see how to get there from
Was it the only string

It works that way in English too. Consider, the only nut:D

Because the adjective "cuerdo(a)" comes from the noun "cordura" (sanity), which is derived from Latin "cordis" (heart), not "chorda" (string). ;)

Thank you very much
That’s great

"She's the only person who isn't nuts around here", something like this.
