Name

A word is could also be defined as a name of an object/ activity etc. 

When Noah sees a "word", he says it is a "name". When he wants to to write the ABCs for the ball I drew, he says write the name here while pointing on the paper where I drew the ball.

We, humans, have named every object/ activity/ animal etc. and given in names using different languages we have created, and in a toddler's utterance of "idea/ thought", I see the very instinctive and intuitive Universal Language beneath all the layers of learned and conditioned language systems, in a raw linguistic form.

Name is not wrong to say, because all the words we have are names. Name is the primary meaning, and word is the secondary meaning. Thus it is no wonder Noah expresses himself saying "name" when he means, in our "learned" adult world "word".

This led me to think: if we can unlearn our language system (before the times of language acquisition involving structures, rules and representations), we might likely find the raw origins of an even more effective language allowing communication universally - the one that likely existed before the "confusion of language" via the Tower of Babel happening.
