Foreign words and phrases
In the Bangla town (Tower Hamlets) area of London many Sylheti (known in the press here as Bangladeshi) words and phrases are now knocking out the native Cockney dialect, and the academic opinion recently expressed in the TV, press and other media in Britain is that 'It is only natural and all right!'. English (British or American) has become the richest language on earth because of such importation of foreign words and phrases.
Widening of minds and the absorption of foreign words and phrases cannot be a bad thing unless it is used for showing off erudition unnecessarily.
