As we have seen in looking at many of the tenses and forms of Lingala verbs, the prefix (beginning) and suffix (ending) of a verb changes to show who or what is doing the action, as well as the tense or time of the action.
Lingala contains additional elements to verbs called extensions or infixes. These are used in a similar way to how we insert –ko– into the future tense verb. They help to create more complex ideas that extend the meaning of the verb root.
For that reason, extended verb roots are listed separately in the dictionary, partly because the extension can change the meaning of the root quite dramatically, and sometimes it does so in ways that are not easily understandable in English.
The following is a list of the different extensions that are used in Lingala, each with a link through to the separate article that explains and discusses their usage:
Not every verb uses each form of extension, and some are rarely used. There is also no best order to learn these, though the causative form is probably the easiest to learn and use.
The following is the order in which they are extended on a verb when combined together:
PREFIX + ko + mi + ROOT + ol + is + el + an + am + SUFFIX
It must be said here that there are no Lingala verbs that would use all these extensions at the same time. But the above guide helps us understand the order in which we should add extensions as we learned how to use them.
