A language learner of Swahili, likely an intermediate student, focused on mastering verb conjugations and grammatical nuances, possibly an autodidact or someone studying through online resources.
I spent a good part of the night, well into the late hours, poring over online Swahili lessons, focusing particularly on the nuances of the verb tenses—past, present, and future—and I must admit, even though it was quite challenging, I felt a strange sense of accomplishment when I finally understood how to use the past perfect tense correctly in a sentence.
