The term 'psychoid' occupies a peculiar and philosophically consequential position in the depth-psychological corpus. Jung borrowed the word from Eugen Bleuler, who had himself adapted it from Driesch's vitalist usage, but Jung's deployment differs sharply from both predecessors. For Jung, 'psychoid' designates processes that are psyche-like or quasi-psychic yet not genuinely psychic in the full sense: they occupy a threshold zone between somatic life-energy and properly conscious or even unconscious experience. This borderland is not the unconscious as such—which extends far beyond it—but rather the infra-psychic region inhabited by instinct at one pole and, at the other, by the archetype in its most transcendent, irrepresentable form. Several commentators—Stein, Romanyshyn, Samuels—have made clear that the psychoid archetype introduces a genuine epistemological crisis: it is a transcendent reality that cannot, in principle, be fully represented in consciousness or in language. Von Franz and Edinger extend the term toward synchronicity and the mind-matter boundary, associating psychoid processes with the pre-conscious coincidence of physical and psychic events. Romanyshyn argues that the psychoid archetype requires psychology to adopt a permanently provisional, humble relationship to its own language. The term thus serves as a conceptual hinge between depth psychology and physics, between instinct and spirit, and between what can be known and what remains constitutively unknowable.

Psychoid for Jung is a term that describes processes that are psyche-like or quasi-psychic but not properly so. The term is used to distinguish psychic functions from vitalistic ones. Psychoid processes lie between somatic life-energy and sheer bodily processes on the one hand and true psychic processes on the other.
Stein offers the clearest definitional statement in the corpus, locating the psychoid as an intermediate category separating vitalistic bodily processes from properly psychic ones, while situating Jung's usage against Bleuler's organ-bound version.
Stein, Murray, Jung's Map of the Soul: An Introduction, 1998thesis
The psychoid process is not the unconscious as such, for this has a far greater extension. Apart from psychoid processes, there are in the unconscious ideas and volitional acts, hence something akin to conscious processes; but in the instinctual sphere these phenomena retire so far into the background that the term 'psychoid' is probably justified.
Jung himself clarifies that the psychoid designates a sub-stratum of the unconscious associated specifically with the instinctual pole, not the whole of the unconscious, and that its justification depends on the virtual disappearance of conscious-like activity at that depth.
Jung, Carl Gustav, The Structure and Dynamics of the Psyche, 1960thesis
Maybe this comparison could be extended to the psyche in general, which would not be an impossibility if there were 'psychoid' processes at both ends of the psychic scale. In accordance with the principle 'natura non facit saltus,' such an hypothesis would not be altogether out of place.
Jung speculates that psychoid processes may bracket the psychic spectrum at both its lower (instinctual) and upper (transcendent) limits, tracing his differentiation from Driesch's and Bleuler's competing definitions.
Jung, Carl Gustav, The Structure and Dynamics of the Psyche, 1960thesis
Speaking of the psychoid archetype, Jung says it is a transcendent reality that is inconceivable in itself. A science of soul cannot know, or name as if it knew, the transcendent, but it can remember in its speaking that it cannot.
Romanyshyn argues that the psychoid archetype compels psychology to adopt a fundamentally provisional linguistic stance, since the term points to a dimension of soul that is constitutively beyond representation.
Romanyshyn, Robert D., The Wounded Researcher: Research with Soul in Mind, 2007thesis
Although, therefore, the psychoid unconscious is unknowable in its own right, its existence for Jung cannot be dismissed or denied. What it does require, as we saw in the first chapter, is an attitude toward language that is always provisional.
Romanyshyn distinguishes the psychoid unconscious as a sui generis reality whose existence is affirmed but whose direct knowability is denied, demanding from depth psychology an epistemologically humble, always-provisional use of language.
Romanyshyn, Robert D., The Wounded Researcher: Research with Soul in Mind, 2007thesis
The confusion obviously springs from the organological standpoint, still observable in Bleuler, which operates with concepts like 'cortical soul' and 'medullary soul' and has a distinct tendency to derive the corresponding psychic functions from these parts of the brain.
Jung criticizes the organological bias in Bleuler's use of 'psychoid,' insisting that the psychologist must resist terminology borrowed from anatomy and attend instead to the totality of experiential process.
Jung, C. G. and Pauli, Wolfgang, The Interpretation of Nature and the Psyche, 1955thesis
The psychoid boundary defines the gray area between the potentially knowable and the totally unknowable—the potentially controllable and th[e uncontrollable].
Stein identifies the psychoid boundary as the conceptual frontier where the will can no longer reach, separating what is in principle accessible to consciousness from what lies permanently beyond it.
Stein, Murray, Jung's Map of the Soul: An Introduction, 1998thesis
This presupposes not only an all-pervading, latent meaning which can be recognized by consciousness, but, during that preconscious time, a psychoid process with which a physical event meaningfully coincides. Here the meaning cannot be recognized because there is as yet no consciousness.
Edinger extends the psychoid concept into the domain of synchronicity and evolutionary pre-history, arguing that psychoid processes underlie the meaningful coincidence of physical and psychic events in the pre-conscious epoch of development.

With the explicit exception of the psychoid unconscious, as this includes things which are not capable of consciousness and are only 'quasi-psychic.'
Jung formally excludes the psychoid unconscious from the selective, volitional activity that defines the psychic proper, marking it as a domain of quasi-psychic content incapable of becoming conscious.

The crisis of language that the psychoid archetype introduces is no less challenging today than the crisis of language introduced with the original notion of the unconscious more than a hundred years ago.
Romanyshyn frames the psychoid archetype as inaugurating a second-order crisis of psychological language, comparable in scope to the original discovery of the unconscious, by pointing to a reality that is neither purely material nor purely psychic.

Samuels' index entry situates the psychoid unconscious as a key conceptual node linking archetypes to biology, instinct, and the somatic dimension of psychic life within his map of post-Jungian discourse.

there are processes with regard to which no relation to the conscious ego can be demonstrated and which yet seem to be 'represented' or 'quas[i-psychic]'
Jung acknowledges a class of processes that are quasi-psychic and that defy straightforward assignment to either consciousness or a representable unconscious, consistent with his broader use of the psychoid concept.

Wiener's index registers the psychoid unconscious as a discrete node within Jungian clinical thought, linking it to the soma-psyche interface and to the neurological and mental aspects of the therapeutic relationship.

Jung maps the psyche as a spectrum, with the archetype at the ultraviolet end and the instinct at the infrared end.
Stein's spectrum model directly contextualizes the psychoid: it inhabits the infrared (instinctual) pole of the psychic spectrum where archetype and instinct are as yet undifferentiated from somatic process.

An index citation from the early Collected Works documents that the psychoid concept appears, at least in nominal form, even in Jung's earlier writings on psychogenesis and mental disease.

Jung was not a pan-psychist, that is, someone who claims that the psyche is everywhere and makes up everything. The body lies outside of the psyche, and the world is far greater than the psyche.
Stein's denial of pan-psychism in Jung is directly relevant to understanding why Jung required a term like 'psychoid': to mark the boundary of the properly psychic without dissolving it into either biology or metaphysics.
