Big Bang

Now I've decided that 'that' is my number one important word, I need to think what other words would make up my four-word vocabulary. I've been thinking about the differences between how a baby would develop a vocabulary and an adult. A baby will certainly add words to his central 'that' based on his immediate environment, and a mind map might look like this:

Of course, the baby won't know the 'category' words - food, object, person, thing - just the things themselves, but a lot more essential words could be added to those two main branches and the following sub-branches. An adult, on the other hand, is perfectly capable of categorising crucial vocabulary in order to make a logical sequence of related words. The starting point of an adult's 'big bang' (I call it this because everything 'explodes' from a central point) could be simply his name.
