xanri -xar- gismu

x₁ [concept] exists in the imagination of/is imagined by/is imaginary to x₂.

Also (adjective:) x₁ is mental (one sense), x₁ is unreal (one sense); in spite of the synonym, note that x₁ is imaginary does not imply that it doesn't exist in the real world; the definition is crafted so that one can talk about imaginary things without claiming that they thereby don't exist. See also fatci, senva, sucta, zasti, cfika, dacti, menli, sidbo.
