Questions & Answers about Дев’ятий урок завтра.
Because дев’ятий means ninth, not nine.
In this sentence, урок is being identified by its order in a sequence, so Ukrainian uses an ordinal number:
- дев’ять = nine
- дев’ятий = ninth
So дев’ятий урок means the ninth lesson or lesson nine, depending on context.
Because дев’ятий behaves like an adjective, and it must agree with the noun урок.
Here:
- урок is masculine
- singular
- nominative
So the ordinal also takes the masculine nominative singular form:
- дев’ятий урок = the ninth lesson
If the noun changed, the ordinal would change too. For example:
- дев’ята сторінка = the ninth page
- дев’яте завдання = the ninth task
