The following text is adapted from Willa Cather’s 1913 novel O Pioneers!. The narrator is reflecting on the landscape. The land was vast and open, stretching endlessly into the horizon, and it stirred within me a faint suggestion of its ancient, untamed spirit. The fields seemed to whisper secrets of the past, and I felt a deep connection to the timeless beauty around me. As used in the text, what does the word "suggestion" most nearly mean?
