The short form of a noun-adjective is the same as that of a noun. This is because a noun-adjective, also known as an adjectival noun, functions similarly to a noun. In this context, a noun-adjective behaves like a noun, allowing it to perform the same grammatical roles. For example, in Japanese, “anzen” (safe) is a noun-adjective that can be used in the same way as a noun. This means that when forming sentences, a noun-adjective can serve as the subject, object, or complement, adhering to the same grammatical rules as a noun. Consequently, the conjugation patterns and sentence structures involving noun-adjectives mirror those of nouns.

Short forms are primarily used to convey direct statements. They serve various purposes, such as in soliloquies, formal reports, and other forms of direct communication. In soliloquies, individuals often use short forms to express personal thoughts or observations succinctly. Similarly, in formal reports or presentations, short forms are employed to convey information efficiently and clearly.

Additionally, short forms play a significant role in conversational contexts, particularly in relationships where there is a sense of closeness or familiarity between speakers. In such situations, short forms are commonly used to facilitate smoother and more relaxed interactions. However, in conversational settings, they are typically accompanied by ending particles that add nuance or emphasis to the statement.
