====== Syncope of /i/ in -/ni/- and -/bi/- ======
Two special phenomena occur if there is no absolutive–ergative pronominal prefix in the pre-stem position.

1. The sequences 𒉌 -/ni/- (locative {-ni-} and personal + directive {-nn-i-}) and 𒉈 /bi/- (personal + directive {b-i-}) acquire the forms -/n/- and -/b/- (coinciding with the ''absolutive–ergative'' pronominal prefixes) before the stem if there isn't already an absolutive–ergative pronominal prefix in pre-stem position. This is typically the case when the verb is used intransitively.<ref>Zólyomi 1993 and 2017, Attinger 1993, Edzard (2003: 98), Jagersma 2010: 468, 477-478; originally posited by Falkenstein.

* {mu-'''ni'''-n-kur} "he brought (it) '''in'''" ({{lit|caused it}}) to go in)' > /mu'''ni'''nkur/, written 𒈬𒉌𒆭 ''mu-'''ni'''-kur<sub>9</sub>'' in early texts, later 𒈬𒉌𒅔𒆭 ''mu-'''ni'''-in-kur<sub>9</sub>''.

In contrast, in an intransitive form, we find a [[Syncope (phonology)|syncopated]] realization:

* {mu-'''ni'''-kur} "he went '''in'''" > /muː'''n'''kur/, written 𒈬𒆭 ''mu-kur<sub>9</sub>'' in early texts, later 𒈬𒌦𒆭 ''mu-u'''n'''-kur<sub>9</sub>''.

The preceding vowel undergoes compensatory lengthening, which is sometimes indicated by its doubling in the spelling:

* {i-'''ni'''-kur} > '''''i<sub>3</sub>-i'''n-kur<sub>9</sub>'' 𒉌𒅔𒆭 "he went '''in'''".

Likewise, the normal realisation of ''bi-'' is seen in:

* {i-'''b-i'''-n-si} > '''''bi<sub>2</sub>'''-in-si'' 𒉈𒅔𒋛 "he loaded (it) '''on it'''".

This is to be contrasted with the syncopated version in an intransitive form:

* {i-'''b-i'''-si} > ''i<sub>3</sub>-i'''b<sub>2</sub>'''-si'' 𒉌𒌈𒋛 "(it) was loaded '''on it'''".<ref>Jagersma (2010: 478)</ref>

The same phonological pattern is claimed to account for the alternation between the forms of the ventive prefix. The standard appearance is seen in:

{i-mu-n-ak} > '''''mu-'''un-ak'' 𒈬𒌦𒀝 "he did it '''here'''".

In an intransitive form, however, we find:

{i-mu-g̃en} > '''''i<sub>3</sub>-im'''-g̃en 𒉌𒅎𒁺'' "he came '''here'''".<ref name=":122"/>
