is_assimilating_back_vowel(symbol)

Determines if the given symbol represents, in Finnish, an "assimilating back vowel". An assimilating back vowel, here, is defined as a back vowel which has a corresponding front vowel and which can trigger or be targeted by vowel-harmony-related assimilations. In other words, this method determines if the given symbol is one of: a, o, u.

Parameters:

symbol - the symbol tested

Returns:

a boolean value indicating if the given symbol represents an assimilating back vowel

is_assimilating_front_vowel(symbol)

Determines if the given symbol represents, in Finnish, an "assimilating front vowel". An assimilating front vowel, here, is defined as a front vowel which has a corresponding back vowel and can trigger or be targeted by vowel-harmony-related assimilations. In other words, this method determines if the given symbol is one of: ä, ö, y.

Parameters:

symbol - the symbol tested

Returns:

a boolean value indicating if the given symbol represents an assimilating front vowel

to_back(symbol)

If the given symbol represents an assimilating front vowel, returns a symbol representing the corresponding back vowel. If not, returns the given symbol itself. Finnish front vowels 'ä', 'ö' and 'y' correspond to the back vowels 'a', 'o' and 'u', respectively.

Parameters:

symbol - a symbol

Returns:

A back vowel corresponding to the given front vowel, or the given symbol itself if it doesn't represent an "assimilating front vowel".

See Also: #is_assimilating_front_vowel(char)

to_front(symbol)

If the given symbol represents an assimilating back vowel, returns a symbol representing the corresponding front vowel. If not, returns the given symbol itself. Finnish front vowels 'a', 'o' and 'u' correspond to the front vowels 'ä', 'ö' and 'y', respectively.

Parameters:

symbol - a symbol

Returns:

A front vowel corresponding to the given back vowel, or the given symbol itself if it doesn't represent an "assimilating back vowel".
