Blog to Learn: The Lexical Evolution:
"Humans have been using a language to communicate for a long time. What started as non-verbal body language and gestures were later complemented by the existence of symbols to convey messages. Hieroglyphics were used by the Egyptians before 4,000BC to document religious scriptures. These symbols were later replaced by the Roman (also called the Latin) alphabet which we all know of - the letters A to Z. These letters are used to form what we call words. Just how many words are there now? The Concise Oxford English Dictionary (11th Edition) Revised 2008 contains over 200,000 words. That's a lot! Come to think of it, we use only a fraction of the number of words in any dictionary in our writings and daily conversations."
