A thing to remember here is that these posts are strictly meant for the particular planet position. Like, today we are looking at Mercury in Aquarius, so the description given here may change for you if your Mercury is although in the sign of Aquarius but with conjunction with or aspected by other planets.
So, lets see what Mercury can do in Aquarius without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent --
Mercury represents communication skills, marketing, calculative ability, younger siblings, hobbies, skills with hands, intelligence, quick decision making, logical thinking, youthfulness etc.
Aquarius is 11th sign of zodiac belt, hence it signifies the things and energy related with 11th house of horoscope, such as Gains, Desires, Hopes and Wishes, Large Organisations, Network Circles etc. Besides this, Aquarius also represents Scientific Thinking & Research, Uplifting the Society, Higher Goals & Rewards for all. Aquarius is made of another set of 2 and half Nakshatra, i.e. Dhanishtha, Satabhisha and Purva-Bhadrapada. Aquarius Lord is Saturn & Rahu.
So, now the planet of intellect is coming into sign of Scientific Research, Higher Thinking etc. The natural result is that these people are going to be very highly intellect and great scientists. These are those people who can not believe in anything unless the evidence is provided. Anything said on hypothesis or without any firm proof is as good as garbage for them. To convince them for something, come with the best arguments, logic and evidence. For making them agree on things like Astrology, you have to give evidence of at least 100 charts on 1 concept then they will agree. But good thing is that they will be ready to give their time in any such research. As it is a sign of Scientific Research and Mercury is all about collecting information, these people are always ready for any research work and if you are able to prove your point once, they will always be with you on that point. Overall, a highly highly intellectual person can be seen from this placement.
But the extent of this impact will always be as per the Nakshatra Mercury is in. In Dhanishtha Nakshatra, it will be impacted by Mars as nakshatra lord. In Satabhisha Nakshatra, Rahu will impact Mercury's functioning. In Purva-Bhadrapada, Jupiter will have its say in Mercury's role in Aquarius.
Also, as the lord of Aquarius, Saturn's & Rahu position will have highest impact on Mercury.
Tomorrow, the last one. Mercury in Pisces/Debilitated Mercury.
