anamorphic (adj.)

"distorted projection or drawing" (one that looks normal from a particular angle or with a certain mirror), 1727, from Greek anamorphosis "transformation," noun of action from anamorphoein "to transform," from ana "up" (see ana-) + morphosis, from morphe "form," a word of uncertain etymology. In botany, "monstrous development of a part" (1830); in evolutionary biology, "gradual change of form in a species over time" (1852).

Middle English -ik, -ick, word-forming element making adjectives, "having to do with, having the nature of, being, made of, caused by, similar to," from French -ique and directly from Latin -icus or from cognate Greek -ikos "in the manner of; pertaining to." From PIE adjective suffix *-(i)ko, which also yielded Slavic -isku, adjectival suffix indicating origin, the source of the -sky (Russian -skii) in many surnames. In chemistry, indicating a higher valence than names in -ous (first in benzoic, 1791).

In Middle English and after often spelled -ick, -ike, -ique. Variant forms in -ick (critick, ethick) were common in early Modern English and survived in English dictionaries into early 19c. This spelling was supported by Johnson but opposed by Webster, who prevailed.
