The concept of grammatical cases was first used in the description of Ancient Greek and Latin grammar, which are fusional languages. Over the centuries the terminology was also used to describe other languages, with very different grammatical structures from Indo-European languages. Some linguists believe that the concept does not fit agglutinative languages very well. Rather than using the "case" paradigm and terminology for describing Hungarian grammar, they prefer to use the terms "(case) suffixes" and "endings". Despite these opinions, nowadays the term "case" is used by most Hungarian linguists.
