words are 1 convenient communication shortcuts 2 not arbitrary symbols 3 unique to each individual in english 4 thoughts written down 4 is correct

No.

I think and speak words more often than I read or write words.

is it 1

i think it is no 2

am i correct please help me

Yes, it's 1.

An infant cries, and the adults guess at what s/he wants. When a child learns to speak, words communicate his needs and wants -- a convenient shortcut that is not available to infants.

Words are arbitrary symbols. A dog is a chien in French and perro in Spanish.

thank you

You're welcome.
