Step-by-step explanation:
Before linguists could study the special sign language of the Bedouin village, they had to overcome the challenge of understanding the language and culture of the Bedouin people. This involved learning about their nomadic lifestyle, their expertise in analyzing their surroundings, and their extensive vocabulary for describing elements of the desert environment. Linguists would have needed to spend time living with the Bedouin people, immersing themselves in their language and culture, in order to gain a deep understanding and proficiency in their sign language. Once they had achieved this level of familiarity with the Bedouin people and their unique language, linguists could begin their study of the special sign language used in the Bedouin village.
