    # Transliteration of above line is: Petrova Lyubov' Stepanovna

    my $gender = detect_gender_by_given_name(@name);
    # $gender == FEMININE

    my @genitive = inflect_given_name(GENITIVE, @name);
    # $genitive == qw/Петровой Любови Степановны/;
    # Transliteration of above line is: Petrovoy Lyubovi Stepanovny

FUNCTIONS

detect_gender_by_given_name

Try to detect gender by name. Up to three arguments expected: lastname, firstname, patronym.

Return MASCULINE, FEMININE for successful detection or undef when function can't detect gender.

Detection rules

When name match some rule, rest of rules are ignored.

  1. Patronym (russian отчество — otchestvo), if presented, gives unambiguous detection rules: feminine patronyms ends with “na”, masculine ones ends with “ich” and “ych”.

  2. Most of russian feminine firstnames ends to vowels “a” and “ya”. Most of russian masculine firstnames ends to consonants.

    There's exists exceptions for both rules: feminine names such as russian name Lubov' (Любовь) and foreign names Ruf' (Руфь), Rachil' (Рахиль) etc. Masculine names also often have affectionate diminutive forms: Alyosha (Алёша) for Alexey (Алексей), Kolya (Коля) for Nickolay (Николай) etc. Some affectionate diminutive names are ambiguous: Sasha (Саша) is diminutive name for feminine name Alexandra (Александра) and for masculine name Alexander (Александр), Zhenya (Женя) is diminutive name for feminine name Eugenia (Евгения) and for masculine name Eugene (Евгений) etc.

    These exceptions are processed.

    When got ambiguous result, function try to use next rule.

  3. Most of russian lastnames derived from possessive nouns (and names). Feminine forms of these lastnames ends to “a”. Some lastnames derived from adjectives. Feminine forms of these lastnames ends to “ya”.
