Editing Quechuan languages (section)

===Morphological type===
Quechua is an [[Agglutinative language|agglutinating language]], meaning that words are built up from basic roots followed by several [[suffix]]es, each of which carries one meaning. Their large number of [[suffix]]es changes both the overall meaning of words and their subtle shades of meaning. All varieties of Quechua are very regular agglutinative languages, as opposed to [[isolating language|isolating]] or [[fusional language|fusional]] ones [Thompson]. Their normal sentence order is SOV ([[subject–object–verb]]). Notable grammatical features include bipersonal [[grammatical conjugation|conjugation]] (verbs agree with both subject and object), [[evidentiality]] (indication of the source and veracity of knowledge), a set of [[topic (linguistics)|topic]] [[grammatical particle|particles]], and suffixes indicating who benefits from an action and the speaker's attitude toward it, but some varieties may lack some of the characteristics.
