"A “yod” is an aspect pattern that some astrologers use.  It involves two planets in a close sextile (60°), with a third planet ‘quincunx’ (150°) to both of the planets in sextile. 
The truth about yods is that they aren’t terribly important, or at least not as much as they are made out to be by some people.
In fact, I would go so far as to say that the yod is one of the most over-hyped configurations in astrology, at least relative to its actual merit."
