nouns and confusion

well back at work, I hit a certain level of confusion. I am loading up on basic nouns. I still can't remeber the words for basics like door, window etc. I keep confusing Nam Ja ( man ) and Nam o ( tree ) it's very interesting calling a man you just met a tree. But I have a ton of phrases adjective and adverbs. So nouns and verys are my next hit. Had a good day with the feral hobbits. Reading the language has been helping but many of vowells throw me because they look alike. If I had it to do over again. I would have learned to read first.
