Final answer:
The inability to understand Meroitic limits our knowledge of Kush cultures, as Meroitic was the indigenous language of the Kingdom of Kush that remains largely undeciphered. It hinders our understanding of Meroitic inscriptions and their historical and cultural significance. Nonetheless, we can still learn about Kush cultures through other sources and influences.
Step-by-step explanation:
Our inability to understand Meroitic affects our knowledge of Kush cultures because Meroitic was the indigenous language of the Kingdom of Kush, but it has not been fully deciphered, so its meaning remains largely unknown to us.
Meroitic inscriptions provide important historical and cultural information about the Kush`ite civilization, including the names of rulers and significant events. Without a complete understanding of the language, we are limited in our ability to fully comprehend these inscriptions and unlock their wealth of knowledge.
