The important thing is that in every Spanish-speaking country the future of querer is querré. Una mesa is a table everywhere. Gracias will always be thank you. Compraría una casa si tuviese dinero will be understood by all speakers of Spanish. 95 percent of the Spanish vocabulary is shared and the rest is anecdotic. More important still, the spelling, unlike English, is the same in all countries.
