An ʿalam is a proper name assigned to a particular person, place, or other entity. ʿAlamiyya means the property of being such a name.
Both زَيْدٌ and عُمَرُ are proper names, but they do not have the same declension pattern. Name status alone does not make every name a diptote.
| Word | Meaning |

| زَيْدٌ | proper name, fully declinable |
