Ethnologue does not specify for which Sardinian variety the lexical similarity was calculated. "-" denotes that comparison data are not available. In the case of English-French lexical similarity, at least two other studies[3][4] estimate the number of English words directly inherited from French at 28.3% and 41% respectively, with respectively 28.24% and 15% of other English words derived from Latin, putting English-French lexical similarity at around 0.56, with reciprocally lower English-German lexical similarities. Another study estimates the number of English words with an Italic origin at 51%, consistent with the two previous analyses.[5]
