After dešimt (ten), of course, go the following numbers:
11 vienuolika
12 dvylika
13 trylika
14 keturiolika
15 penkiolika
16 šešiolika
17 septyniolika
18 aštuoniolika
19 devyniolika
They act the same as dešimt: they require the plural genitive case:
vienuolika futbolininkų (11 footballers)
dvylika futbolininkių (12 female footballers)
However they have cases: Nominative case:
Genitive case (of):
Dative case (to/for):
Accusative case:
Instrumental case (using):
Locative case (in):
trylika
trylikos
trylikai
trylika
trylika
trylikoje
keturiolika
keturiolikos
keturiolikai
keturiolika
penkiolika
penkiolikoje
Their endings are just like of feminine nouns (-a), except for the accusative case: the accusative case exactly like the nominative - without the nasal ą.
