[1] Olo is believed to be a Goal Oriented Activation language, meaning the speaker chooses their words with an idea of what they are trying to achieve with the listener in mind,[2] this has been labeled as referential theory.
Referential theory has been divided into four groupings, all of which come with disadvantages, recency, episodes, prominence, and memorial activation.
Olo is classified as an SVO (subject, verb, object) language under normal circumstance, but, in certain cases, the object can be fronted, the subject can continue on as a free noun, or there can be occurrences similar to passive tense in English.
The prefixes that attach to the verb serves as markers for the subjects and gives the listener information about the person, number and gender.
