What is the difference between "yo" and "yo" with another word?

For example, "Yo estudio ingles." I know that means I study English. But in another example it said "Estudio espanol." What is the difference between yo estudio and estudio? Does it mean you give yourself more respect or what? Please help or I'll fail Spanish!!What is the difference between "yo" and "yo" with another word?
Unlike English, in Spanish there are many things that are redundant, and they are used in order to emphasize according to speaker's choice. This is tricky since natives from different countries have their own usual ways. "Yo" as such every pronouns can be used when you want to draw the attention of people.



Another example of redundancy:



"I said John"



In Spanish you can say:



-"Dije a John" or "Le dije a John" [preterite]

-"Dec铆a a John" or "Le dec铆a a John" [imperfect]



BUT natives always prefer the second form, sometimes, repeating helps you to undertand something better. This aspect show the diference between who are natives and not.
It is more common not to use the pronoun in Spanish, since the verb already includes it [estudio=I study]. It is only added when you want to give special emphasis to the subject, or when you want to avoid a possible ambiguity in the third person singular between he/she/it or in the third person plural between they/you.What is the difference between "yo" and "yo" with another word?
remember the ending of the verb "includes" the person



for example



yo estudi-o

tu estudi-as

el/ella/eso estudi-a

nosotros estudi-amos

ustedes estudi-an

ellos estudi-an



you never say "yo estudia" o "yo estudiamos" for that reason when you say "estudio" is obvious "yo estudio" in spanish is called "sujeto tacito" subject tacit.



recommendation: use "yo" one time and then use subject tacit.

for example



Yo estudio, trabajo, viajo, camino, corro, etc.What is the difference between "yo" and "yo" with another word?
In Spanish the verb shows the pronoun used.You do not need to include the pronoun except for -usted or if the meaning is not clear.Examples- 驴C贸mo est谩s? How are you? but 驴C贸mo est谩 usted? Estoy bien.-I am well.

Voy a casa-I go home.
Adding the "yo" makes it proper and just makes it clear what u are saying.
If u were trying to say "she studies English" you could say "Ella estudia ingles" or you can say "estudia ingles" however "estudia ingles" can mean she, he, or it studies English. So the prOnoun is just to clear everything up! The "yo" isn't nessecary.
