Editing Subjunctive mood (section)

===Akkadian===
Subordinate clauses in [[Akkadian language|Babylonian]] and Standard Babylonian [[Akkadian (language)|Akkadian]] are marked with a ''-u'' on verbs ending in a consonant, and with nothing after vocalic endings or after [[ventive]] endings. Due to the consonantal structure of semitic languages, and Akkadian sound laws, the addition of the -u might trigger short vowels in the middle of the word to disappear. [[Akkadian language|Assyrian]] Akkadian uses a more complicated system with both -u and -ni as markers of subordination. The ending -ni was used in the instances where -u could not be used as stated above. During Middle and Neo Assyrian the -ni ending became compulsory on all subordinate verbs, even those that already had the -u, resulting in -ni and-ūni as markers of subordination.<ref>Huenergard, John, ''Grammar of Akkadian Third Edition'', Eisenbrauns 2011</ref>
