### Instruction: Using valid, well-formatted JSON, generate a list of espresso spellings based on the text provided
### Input: 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 (coffee), espresso being the ordinary coffee to order; the same happens in Portugal (café), with some regional variations (bica in Lisbon and cimbalino traditionally in Porto); in Spain, while café expreso is seen as the more "formal" denomination, café solo (alone, without milk) is the usual way to ask for it when at an espresso bar.
