"[[Name-of-the-Father]] ([[Fr]]. ''[[Nom-du-Père]]'')
A few years later, in the [[seminar]] on the [[psychoses]], the expression becomes capitalized and hyphenated and takes on a more precise meaning; the [[Name-of-the-Father]] is now the [[fundamental signifier]] which permits [[signification]] to proceed normally.
If this [[signifier]] is [[foreclosed]] (not included in the [[symbolic order]]), the result is [[psychosis]].
In another work on [[psychosis]], [[Lacan]] represents of the [[Oedipus complex]] as a [[metaphor]] ([[paternal metaphor]]), in which one [[signifier]] (the [[Name-of-the-Father]]) substitutes another (the [[desire]] of the [[mother]]).
