Checks if a term could be stemmed.

Delete suffix e if in R1 and preceded by a non-vowel, and then undouble the ending

Delete "heid"

A d-suffix, or derivational suffix, enables a new word, often with a different grammatical category, or with a different sense, to be built from another word. Whether a d-suffix can be attached is discovered not from the rules of grammar, but by referring to a dictionary. So in English, ness can be added to certain adjectives to form corresponding nouns (littleness, kindness, foolishness ...) but not to all adjectives (not for example, to big, cruel, wise ...) d-suffixes can be used to change meaning, often in rather exotic ways.

undouble vowel If the words ends CVD, where C is a non-vowel, D is a non-vowel other than I, and V is double a, e, o or u, remove one of the vowels from V (for example, maan -> man, brood -> brod).

Substitute ä, ë, ï, ö, ü, á , é, í, ó, ú
