The distance between Portuguese and Spanish is: 16,7

These languages are very closely related!

*Statistical context of this comparison: The statistical expected value is 84,2 with a standard deviation of 5,1. The probability to get a distance of 16,7 or less by chance is 0,0%.

The more red zone is covered by the orange vertical result line on the graph, the higher is the probability that the result is due to chance. The farther right the line is in the green area, the closer the langages are related.

The distance between the two languages is expressed as a value between 0 (same language) and 100 (biggest possible distance). In practice, the values reflect approximately following degree of relatedness:

Between 1 and 30: Highly related languages. Protolanguage (common “ancestor”) between several centuries and approx. 2000 years.
Between 30 and 50: Related languages. Protolanguage approx. between 2000 and 4000 years.
Between 50 and 70: Remotely related languages. Protolanguage approx. between 4000 and 6000 years. Chance interference increases with values above 60-62.
Between 70 and 78: Very remotely related languages. Protolanguage approx. older than 6000 years - but high potential of interference with chance ressemblance.
Between 78 and 100: No recognizable relationship: the few ressemlances measured are more likely to be due to chance than to common origin!

The average distance between all languages of this study is 71,8. The average statistical expected value is 83,36 with an average standard deviation of 5,03. The expected values and expected standard deviations stated in the pairwise comparisons are specific to these comparisons and reflect their own exposure to chance.
