Final answer:
The 'Late Egyptian' language falls under the Late Kingdom Egyptian Dynasties, which existed from 1366 BCE to 332 BCE. It is part of the later period of Egyptian history.
Step-by-step explanation:
The 'Late Egyptian' language falls under the Late Kingdom Egyptian Dynasties, which existed from 1366 BCE to 332 BCE. This period marked the height of the Egyptian Empire and included great pharaohs such as Hatshepsut, Thutmose 3, Akhenaten, and Tutankhamun.
During this time, the Egyptians continued to develop their standardized written language for literary texts. However, after 600 BCE, Egypt was controlled by the Persians and the Egyptian Empire slowly declined.
Therefore, on a scale of 1-5 with 1 being the oldest and 5 being the newest, the 'Late Egyptian' language would fall at a 4, as it is part of the later period of Egyptian history.
