«أَوْ خَيَالِيٌّ»
Or the link may be imaginative.
An imaginative jāmiʿ arises when imagination brings two images together in the compositive faculty, especially because they have been associated before. The presence of one image prompts the recollection of another.
Such association may grow from individual experience, repeated observation, or familiar usage. The concepts need not share an intellectual identity or true logical contrariety.
