Compare  allows the user to determine the degree of correspondence between basic dictionaries of two languages and then, using Ch. Swadesh’s formula, to estimate time depth separating two genetically related languages, i.e. to find out at what time the two languages separated from their proto-language.

When working with Compare the user is required 1) to compile basic dictionaries for two languages or use/modify existing ones. Compare contains a basic dictionary for English compiled by Swadesh; 2) to set correspondences between symbols in pairs of words using some laws of languages historical development (Grim’s law, Verner’slaw for Germanic languages). For example, initial consonants can be safely identified in English drink and German trinken; 3) to compute time depth by Swadesh’s formula.Compare can work with any pairs of languages that use Latin or Cyrillic alphabets.
