Timdiemthi Hi there! As for humans, the age of learning new things and understanding the new ideas and beliefs more is never over and it is only done when the person leaves the world. Also, as our natural property, we are always into knowing something in the back of our minds. When as a teenager we are going on with our studies, then too we are learning though we like it or hate it. We incorporate the use of dictionaries and different other vocabulary building tools to help websterus learn things more easily. We thus get a primary education necessary for us for a sound future life. Then, when we step into our practical life, we use tools to help us understand the things present in our job and fields related to it and then we are repeating the process for our family and so on. Basically, we always are learning something or want to learn it. For this either we consult dictionaries to understand the term or use Google it to understand even better than the only available information in dictionaries. Secondly, with everything available on internet, dictionaries too are also made available on the internet.
