I remember learning this in primary school, but yeah, it's not beginner stuff. It comes pretty near the end of the course though ... so if the rest of the course was actually fleshed out and not just single-word flashcards with the occasional sentence, it might not seem so out of place because you we wouldn't feel like such absolute beginners at the end of the course.
Thanks for your reply, and yes, very true. I also have a Swahili book that I am learning with, as I don't think that this course alone will get me to the level where I can actually use Swahili with any confidence. It's interesting though to hear that you learned this word in primary school. I am not a native English speaker, and in my 18 years of living in Ireland I haven't come across this before, and hadn't expected to learn new English words in a basic Swahili course :-).
It's something you learn in English literature when studying poetry. Usually about 5th or 6th grade. (which may be middle school now, depending on where you live). I actually had to look it up to refresh my memory, because it just isn't a word I use often and it gets mixed up with the other poetic terms I learned about the same time.
