You’ve probably heard of Spanglish, Hinglish and Chinglish. The Guardian has a piece on its website about Uglish, a version of English spoken in Uganda. Some Uglish words will be recognisably English to speakers elsewhere, eg dirten to make dirty, cowardise to behave like a coward, and wiseaching acting like a wiseacre. Others, however, being influenced by Luganda and other local languages, will not be familiar to English speakers elsewhere: mazongoto a big bed, and wolokosso loose talk.
For more Uglish words and details of a book on the topic by Bernard Sabiti, see the Guardian page.
