Simplified Grammar of the Hungarian Language/Accidence
ACCIDENCE.
The parts of speech are the same as in other languages—viz., Nouns, Verbs, and Particles.
Of these the nouns (substantive, adjective, numeral pronoun) and verbs undergo certain modifications in order to express the various accidental circumstances of number, case, person, time, and place. These modifications are called inflections; and the defining particles joined to the words are called suffixes.
Particles are not inflected, but are used to define the noun or verb.
