Using valid, well-formatted JSON, generate a list of espresso spellings based on the text provided

Context: The spelling expresso is mostly considered incorrect, though some sources call it a less common variant. It is common in French and Portuguese. Italy uses the term espresso, substituting s for most x letters in Latin-root words; x is not considered part of the standard Italian alphabet. Italian people commonly refer to it simply as caffè, espresso being the ordinary coffee to order; the same happens in Portugal, with some regional variations; in Spain, while café expreso is seen as the more "formal" denomination, café solo is the usual way to ask for it when at an espresso bar.

Answer: espresso, expresso, coffee, caffè, café, bica, cimbalino, café expreso, café solo
