Ask any of your American friends or colleagues if they use "outrightly" as the adverb of "outright." It is merely to let people know that it's nonstandard, that the educated native speakers of the language don't use it. On the part of Professor Aluko he wrote inter alia thus, "May I confess that in my 1970 WAEC, I got an A1 in English Language and Physics, A2 in Literature, Mathematics and Chemistry and A3 in French and Biology (with a torrid C4 which leaked in my year and had to be re-taken)." My questions to you Professor Harrow are these:
"Heshima yangu kubwa haitokani na utajiri, maana kama utajiri wako hauna msaada wala kugusa watu masikini hauna maana yeyote, hivyo basi heshima hii ni kutokana na kwanza bidhaa zangu kugusa maisha ya watu kila siku kuanzia sukari na majani ya chai asubuhi pamoja na unga wa ngano, lakini pia chakula cha mchana kwa unga wa sembe, mafuta ya kupikia na maji ya kunywa, bidhaa zote hizo za Mohammed Enterprises zinagusa maisha kila nyakati katika siku.
