Earlier quoted context omitted.
The snopes debunking of Nova/no-va insists that native Spanish speakers wouldn't automatically see the similarity and irony between the words. They did, just as English speakers did for EE. Though they both may have sold well in spite of the meaningful names.
Well, as I wrote earlier, as someone who has been fluently reading and listening to Spanish conversation, TV, magazines and books since childhood, I find it hard to believe that any significant number of Spanish speakers would automatically read the irony.
In case you're still reading this: do you mean to say the Spanish speaking world is less interested in wordplay and prone to notice such puns?
