retrograde Mercury rules 5th and 8th house is in 1st house in Aquarius
As a Jyotish astrologer, I would interpret the placement of retrograde Mercury in the 1st house of Aquarius sign as follows:
Aquarius is an airy sign, ruled by Saturn, and known for its independent, unconventional and analytical nature. With Mercury being retrograde in this sign, there may be a tendency for the individual to think differently or communicate in a unique way that is not always understood by others.
The first house represents self-expression, personality, mentality and appearance. With the influence of Mercury retrograde, the individual may struggle to communicate their thoughts effectively or may be prone to overthinking. They may experience difficulties in expressing themselves verbally or may feel misunderstood by others.
However, as Mercury is a planet of intelligence and analysis, retrograde Mercury can also give the individual a sharp and perceptive mind, capable of critical analysis. They may possess an innate curiosity and enjoy exploring new ideas and concepts.
Overall, the placement of retrograde Mercury in the 1st house of Aquarius can bring both challenges and opportunities for growth. The individual may need to learn how to express themselves more effectively while also honing their analytical skills to gain greater insights into the world around them.
