    chound, what is not clear in the wikipedia article.

    The key point is:
    In the two phase diagram given, the eutectic is found at the "V" of the liquid phase, where the vertex touches the horizontal line. The horizontal line represents a constant temperature, and the vertex represents a specific composition. The eutectic represents the point where that composition goes 'directly' from solid to liquid, i.e. without partially melting to a solid-liquid combination.

    The example of the steel (Fe - C) system is perhaps better.
    This figure shows the eutectic and eutectoid.

    Then there is a three-phse reactions diagram below that:

    which should be more clear.

    Here is another site which discusses binary phase diagrams.
