37. Adverbs derived from Nouns, when not formed with the Locatives, or ya, ye, or yo, are simply preceded by the Article ; this will be apparent from the list on page 604. When such an Adverb is brought out of its normal position,so that instead of following the Verb, it precedes it, the Article is dropped. The following Adverbs of time may take their Article when they precede the Verb, when they are highly emphatic: --o fuku, e mbanu, nganu, mbatu, o ngatu, o masika, o mbazi, o unu, o elelo. In the same way the Locative Adverbs and Prepositions take the Article as a Prefix, when specially emphatic, and preceding the Verb.
