"Language surrounds us every day and we know how to recognise it" 


- On this statement  we can see and realise that  in  any single act of communication there is always language involve, of any type, of any form, but is still language.  From the common act of going to the market to realising a test there is a sort of language involve. Everyone on a specific community  has  understand and recognise the words that  form part of that specific language.




"A word is one or more sounds that in combination have a specific meaning assigned by the language"


- After thinking  for some time,  you realise that words are conformed of  letters, and to say letters you need to make sounds, so words are a combination of sounds that a specific society assigned to name something, for example  the world "chair", everyone who speaks English will understand the same thing.




"The most powerful tool known is the one we use to build every other tool"




- This one states that without language we would not be where we are now. Without language there would not exist communities, therefore there could be no type of organisation to build a fabric or something else more important. We could not express what we know, so there would be no education and everyone will have to make things on their own. Basically here is state that language is a fundamental tool for the progress and development of society.
