Editing Sundanese language (section)

====Plural form====
Other Austronesian languages (especially those in western Indonesia) commonly use [[reduplication]] to create plural forms. However, Sundanese inserts the ''ar'' infix into the stem word. If the stem word starts with ''l'', or contains ''r'' following the infix, the infix ''ar'' becomes ''al''. Also, as with other Sundanese infixes (such as ''um''), if the word starts with vowel, the infix becomes a prefix. 
Examples: 
#''Mangga téh, t'''ar'''ahuna haneut kénéh''. "Please ma'am, the bean curds are still warm/hot." The plural form of ''tahu'' 'bean curd, tofu' is formed by infixing ''ar'' after the initial consonant. 
#''B'''ar'''udak leutik l'''al'''umpatan.'' "Small children running around." ''Barudak'' "children" is formed from ''budak'' (child) with the ''ar'' infix; in ''lumpat'' (run) the ''ar'' infix becomes ''al'' because ''lumpat'' starts with ''l''.
#''Ieu kaén batik '''ar'''alus sadayana''. "All of these batik clothes are beautiful." Formed from ''alus'' (nice, beautiful, good) with the infix ''ar'' that becomes a prefix because ''alus'' starts with a vowel. It denotes the adjective "beautiful" for the plural subject/noun (batik clothes).
#''Siswa sakola éta mah b'''al'''ageur.'' "The students of that school are well-behaved." Formed from ''bageur'' ("good-behaving, nice, polite, helpful") with the infix ''ar'', which becomes ''al'' because of ''r'' in the root, to denote the adjective "well-behaved" for plural students.

However, it is reported that this use of ''al'' instead of ''ar'' (as illustrated in (4) above) does not to occur if the 'r' is in onset of a neighbouring syllable. For example, the plural form of the adjective ''curiga'' (suspicious) is ''caruriga'' and not *''caluriga'', because the 'r' in the root occurs at the start of the following syllable.<ref>{{Cite book |title=The Phonology of Consonants: Harmony, Dissimilation, and Correspondence |last=Bennett |first=Wm G. |date=2015 |publisher=Cambridge University Press |location=Cambridge |pages=132 |language=en}}</ref>
 
The prefix can be reduplicated to denote ''very-'', or the plural of groups. For example, "b'''arar'''udak" denotes many, many children or many groups of children (''budak'' is child in Sundanese). Another example, "b'''alal'''ageur" denotes plural adjective of "very well-behaved".
