Open and Closed Word Classes

[Toivo]

Different languages have different word classes as open class and closed class – for example, in English, pronouns are closed class and verbs are open class (see for example the contentious topic of gender-neutral pronouns in English and how common verbing is), while in Japanese, pronouns are open class, while verbs are closed class – to form a new verb, one suffixes 〜する (-suru, "to do") to a noun – for example, "to exercise" is 運動する – "to do exercise".

Хотелось бы узнать, в каких ещё языках кроме японского и баскского глаголы являются "закрытым классом"?
