State of being joined or fastened together; union by an intervening substance; relation by blood or marriage; a religious sect.

Acquaintances; business friends. Note.-By most writers the spelling connection and connexion are used indifferently. As derived from the English verb connect and the Latin necto, the spelling connection should be preferred to that of connexion. If, however, both forms are preserved, their application ought to be restricted, and they ought not to be made identical in signification. As suggested by Dr Latham, the form (1) connection should be used when a link or bond of union is meant; and (2) connexion when the object which is linked is signified-thus.
