The word "fore shadows" refers to the suggestion or indication of something in advance. The antonym for this could be words like "unpredictability," "surprise," or even "spontaneity." These words connote the opposite of fore shadows, which suggests a preconceived notion of what will happen soon. When something is unpredictable, one has no idea what might happen in the future. Similarly, the element of surprise suggests that the unexpected is about to happen. Lastly, when something is spontaneous, it means that it is happening on the spot without any prior thought or planning, further emphasizing the opposite of fore shadows.
