Which letter in the Spanish alphabet is used only to pronounce words from another language?

Answer : The only letter was the W, because there weren't Spanish words with this letter, but for some years now, the Royal Spanish Academy has accepted some foreign words within the Spanish language, naturally complying with the Spanish spelling rules. One of them is the word wéstern, which comes from English and which is a flat word, because its tonic syllable is the penultimate and as it ends with two consonants, it must have a written accent.
