I just realised how TT forum has helped me a lot with my English. Every now and then I would type a new word without realising that I actually don't really know that word - it happened automatically. I suppose because I often hear that word often on TV or on radio. Today I typed the word 'appall'. I was amazed because I didn't even know how to spell it and I just typed it like that and somehow I knew that the word is related to disgust, revolt, or something like that.
