The main purpose of this work is to approach each one of the radicals used by the Spanish language to make up the « verb ir ». Reappraising the category known as « auxiliary » and completing a detailed analysis of the combinations in which this verb is to be found [that explain the sense effects produced in discourse] leads us to the assumption that the verb ir only exists through different significant radicals, each of them bearing its own – its one and only – meaning. It is therefore impossible to consider that the « verb ir » has only one meaning, as it is a conglomerate of heterogeneous paradigms that all share a common feature : the « tension towards ». This study also tries to define the links between those verbal forms, grouped under the infinitive ir, and other Spanish verbs such as venir, andar, ser or estar.
