Today I read this comment in the Csound mailing list see full post (emphasis mine):
The interface could be polished, IMO, but the idea is sound [...]
it took me (as a German native speaker) a while to understand its meaning. Then I remembered that there is also the adjective sound. Because the Csound mailing list is dedicated to sound and also the post subject could be meant here, I thought it could be also an intended ambiguity.
Is it therefore reasonable to expect that the pun "sound idea" (for "idea for a specific sound" and "reasonable idea") would work for English speakers?
