nyílhatnak
Nyílhatnak is a Hungarian verb form. It is the third-person plural potential mood, present tense of the verb "nyílik" which means "to open". The suffix "-hat" or "-het" indicates possibility or permission, and "-nak" or "-nek" is the third-person plural ending. Therefore, "nyílhatnak" translates to "they may open", "they can open", or "they might open". This form is used when there is a possibility or permission for multiple subjects to open something. For example, "Az ablakok nyílhatnak" means "The windows may open". It implies that the opening of the windows is possible or allowed, but not necessarily happening. The context of the sentence determines the precise nuance of possibility or permission. It is a common verb conjugation in Hungarian grammar, frequently encountered in spoken and written language.
