analytic language
  زبان ِ آنالسی   
zabân-e ânâlasi

Fr.: langue analytique   

A language that is characterized largely by the fact that it depends on word order, rather than on inflections (grammatical endings), to convey sentence meanings.

anamorphosis
  آناریخت‌مندی   
ânârixtmandi

Fr.: anamorphose   

1) Optics: The formation of a distorted image by an → anamorphic system.
2) Biology: The evolution from one type to another through a gradual and steady process of changes.
3) Art: A distorted image that appears in proportion when it is viewed from a specific point of view or reflected in a curved mirror, or with some other optical device.

From Gk. anamorphosis "transformation," noun of action from anamorphoein "to transform," from → ana- "up," + morphe "form" + -sis a suffix forming abstract nouns of action, process, state, condition, etc.

Ânârixtmandi, from ânâ- "up," + rixt "morphe," → morphology, + mand, → -ist + noun suffix -i.
