retrograde Mercury rules 9th and 12th house is in 8th house in Taurus

As a Jyotish astrologer, I would interpret a retrograde Mercury in the 8th house in Taurus sign in the following ways:

1. Communication struggles: Retrograde Mercury tends to cause communication issues, leading to misunderstandings, delays, and miscommunications. This placement is in the 8th house, which governs secrets, transformation, and major changes. Therefore, communication issues may arise when it comes to sharing secrets, undergoing transformative experiences, or handling major changes in life.

2. Financial setbacks: Taurus is a sign associated with finance, wealth, and possessions. Retrograde Mercury in Taurus can cause financial setbacks, leading to delays or obstacles in acquiring wealth or dealing with financial matters. The 8th house further emphasizes financial matters related to investments, inheritance, or hidden sources of wealth.

3. Intuitive insights: On the positive side, retrograde Mercury can enhance intuitive abilities, allowing the native to gain insights into mysteries and hidden information. The 8th house's association with psychic and occult matters can further facilitate intuitive insights and transformative experiences.

4. Inquisitive mind: Mercury is the planet of intellect, curiosity, and analytical thinking. Even when retrograde, Mercury can enhance the native's inquisitive mind, leading them to explore deeper meanings, hidden secrets, and unconventional approaches.

5. Health issues: The 8th house also governs health issues related to chronic ailments, surgeries, and diseases. Retrograde Mercury can indicate health issues related to communication channels, the throat, lungs, and nervous system. The native needs to take care of their health and seek timely medical advice.
