If you mean direction, e.g. 'to London', 'a'; so 'a londres' = 'to London'
If you mean the first half of an infinitive, e.g. 'to travel', 'to eat', 'to live', 'to' is communicated by various infinitive endings. For the verbs in question, these are:
viajAR = to travel
comER = to eat
vivIR = to live
The infinitive-endings are in capitals simply to clarify them here (though,as it happens, the capitals also indicate the stress on the spoken words).
you say yo
you would say yo
Yo tengo or just "tengo" is the word in Spanish for "I have"
I do not is no hago in spanish.
The Spanish word for boy is "chico" ( chEEko)

It is not necessary to capitalize the word "yo".
