The Uncanny stands in opposition to the heimlich, what is in the lexicon Freud shares from Theodor Reik that follows, homely, "belonging to the house or the family," contained, "of animals: tame, companionable to man," as opposed to wild. Heimlich also means "intimate, friendlily comfortable."
However, the further definition of heimlich pivots until it becomes almost synonymous with the unheimlich/uncanny—"Concealed, kept from sight, so that others do not get to know of or about it, withheld from others." Heimlich can also be used in ways that describe the occult or unconscious, with the "notion of something hidden and dangerous." (Grimm, 1877)
