Forming negative sentences in the future perfect continuous tense is straightforward. We can do so by adding "not" after the auxiliary verb "will" or "am/is/are" to indicate negation. This method is consistent with other future tenses, making it easier to remember! 😊
Example:
1. The scientists will have been working on the experiment for two years by the end of 2025.
2. By this evening, she will have been practicing the piano for three hours.
3. The athletes will have been running for hours by the time the sun sets.
