What is the Venus Squaring Mercury transit like?
In my opinion, this aspect causes the mind and feelings to be temporarily separated, the mental cnditions tending to go against the feeling or emotinoal side of the nature. One can expect errors of judgment and a general condition in which affairs for the time may go adversely so fas as minor detairs are concerned. With this aspect, one can mildly criticise, and feel somewhat out of gear in parts of your composition. Financially, one needs to carefully watch this especially where correspondence is concerned, avoiding litigation and general dealings with solicitors. Having pointed this out, I agree with Vic that the transit cannot promise you what the natal chart doesn’t have. So if this aspect, whether Mercury squares venus or vice-cersa, is present in the natal chart, then a transit will awaken this aspect. You would have to look at the houses involved to see what area is affected with this transit.
