From what I can tell...
"Digo" is like "say" in that it tends to come with what the person says. I say yes/Eu digo sim
"Falo" is like "speak" as in the action of speaking. I speak with him/Eu falo com ele.
You wouldn't ask someone what thay spoke, you'd ask them what they said. And you wouldn't ask someone to say with you, you'd ask them to speak with you.
Is this correct?
yes. and in order to complete your thoughts: "contar" is "to tell" and "to count"
In this case they are synonyms.
In general, "dizer" is more like "to tell" or "to say", while falar is more like "to speak".
Digo refers to the say or said Falo refers to the word speak for example i don't speak Spanish you would use falo I am speaking you would use falo I say, you are beautiful you would use digo I said not to do that Digo
So what are the different conjugations for the verb digo? Past, present, future. He, she, they, etc, etc, etc?
Would "I said yes" also be right? Or is there a different verb form for the past tense that i just haven't gotten to?
