Thirdly, a lot of adopted words were synonymous to native, which however didn’t result in replacement. Both words survived as they differed in style, shaes of meaning or combinability (French loan-words preserve a more bookish, literary character). This influx (наплыв, прилив) of French words is one of the main historical reasons for the abundance of synonyms in ModE:
commence-begin, search-look for, odour-smell, desire-wish, existence-life, language-tongue, felicity-happiness, enter-come in, continue-go on, solar activity-sunglasses, maternal unkle-motherly love.
As a result of the Conquest, the English language changed greatly under the influence of the French language. The two languages gradually formed one rich English language, which already in the 14^th century was being used both in speech & in writing. Gradually the Normans mixed with the Anglo-Saxons & the Danes & from this mixture the English nation finally appeared.
