The focus of the paper is to offer a different perspective for the study of Spanish potentiality (or the epistemic modality). It presents a number line that is used to illustrate the relations that can be found between reality and potentiality, and a methodology that makes it possible to place utterances that express potentiality on this line. Special attention is paid to the question of mood selection and also to the lexical expressions of this type of modality. The paper claims that the influence the use of subjunctive or indicative has on the modality of an utterance differs according to the character of the lexical expression of potentiality that precedes it.
