'Amorite-style' originates from English, specifically the word 'Amorite', where 'Amorite' ultimately derives from Akkadian 'Amurru' (also reflected in West Semitic/Hebrew forms) meaning 'Amorite' or 'western (people/land)'.

'Amorite' changed from Akkadian 'Amurru' into Northwest Semitic/Hebrew 'ʿAmori', then entered classical languages and later English as 'Amorite', and compound usage such as 'Amorite-style' developed in modern English to denote 'in the manner of the Amorites'.

Initially it referred specifically to the people or region called 'Amurru' (the Amorites/westerners), but over time it has been used adjectivally to mean 'pertaining to' or 'in the style of' the Amorites; 'Amorite-style' denotes that stylistic relation.
