«والثانية موضوعة لمجرد ثبوت المسند للمسند إليه»
The second type, the nominal sentence, fundamentally expresses the establishment of a predicate for its subject.
“الشَّمْسُ مُضِيئَةٌ”
“The sun is luminous.”
The sentence establishes luminosity as a predicate of the sun without specifying one particular moment merely by its nominal construction.
“الْعِلْمُ نَافِعٌ”
“Knowledge is beneficial.”
Benefit is attributed to knowledge.
A nominal sentence does not automatically establish everlasting continuity. Permanent or temporary duration is inferred where the surrounding wording or context warrants it.
