ETYMOLOGICAL DOUBLETS

Sometimes a word is borrowed twice from the same language. As the result, we have two different words with different spellings and meanings but historically they come back to one and the same word. Such words are called etymological doublets. In English there are some groups of them:
Latino-French doublets.
Latin English from Latin English from French
uncia inch ounce
moneta mint money
camera camera chamber

Franco-French doublets
doublets borrowed from different dialects of French.
Norman Paris
canal channel
captain chieftain
catch chaise
Scandinavian-English doublets
Scandinavian English
skirt shirt
scabby shabby
There are also etymological doublets which were borrowed from the same language during different historical periods, such as French doublets: gentil - любезный, благородный, etymological doublets are: gentle - мягкий, вежливый and genteel - благородный. From the French word gallant etymological doublets are : ‘gallant - храбрый and ga’llant - галантный, внимательный.
Sometimes etymological doublets are the result of borrowing different grammatical forms of the same word, e.g. the Comparative degree of Latin «super» was «superior» which was borrowed into English with the meaning «high in some quality or rank». The Superlative degree (Latin «supremus»)in English «supreme» with the meaning «outstanding», «prominent». So «superior» and «supreme» are etymological doublets.
