に他(ほか)ならないNothing but, None other than, Simply

"にほかならない" and "にすぎない" are similar in that they both emphasize the simplicity or minimalism of something. However, "にほかならない" is used to highlight the significance or importance of that simplicity, translating to 'Nothing but, None other than, or Simply'. It expresses the idea that something or someone is of utmost importance or significance. On the other hand, "にすぎない" downplays the importance of the subject, translating to 'No more than, Just, or Merely'. It portrays the subject as being minor or unremarkable.

The key difference between しか～ない and にほかならない lies in the context of usage. The expression しか～ない conveys an idea of limitation or scarcity, highlighting that only a specific condition or item exists, often used in a negative sense. On the other hand, にほかならない is used to emphasize the sole identity or exclusivity of something, placing stress on it being the only option or choice.

The key difference between だらけ and にほかならない is fundamentally based on their nuances and usage. だらけ suggests a negative state where something is "covered in" or "full of" undesirable things or conditions, whereas にほかならない expresses a definitive conclusion or emphasis on something as being "nothing but," "none other than," or "simply" that very thing. While だらけ highlights an unpleasant abundance or excessiveness, にほかならない underlines certainty, exclusivity, or essentiality.

The grammar point にほかならない is used when you want to emphasize that something is simply or only a certain thing or way, signifying exclusivity or singularity. On the other hand, よりほかない is used to express that there is no other choice, way or alternative to doing something, suggesting obligation or necessity. Thus, you use にほかならない to declare that 'It is nothing but this', while よりほかない is used to say 'There's no choice but this'.
