Questions & Answers about Yo me fui cansando un poco en la grada, pero no quería perderme el final.

Why is yo included here? Isn’t Spanish usually a pro-drop language?

Yes. In Spanish, subject pronouns are often omitted because the verb ending already shows who the subject is. So Yo me fui cansando... could also be simply Me fui cansando...

Here, yo is probably included for emphasis, contrast, or a slightly more personal tone. For example, it can suggest something like:

• As for me, I was getting a bit tired...
• I myself was starting to get tired...

It is not required grammatically, but it is perfectly natural.

What does me fui cansando mean exactly?

Me fui cansando uses the structure irse + gerundio. This often expresses a gradual change over time.

So me fui cansando means:

• I gradually got tired
• I started to feel more and more tired
• I was getting tired little by little

It is not the same as simply me cansé, which usually means I got tired or I became tired as a more complete event.
With me fui cansando, the sentence highlights the process.

Why is ir used in fui cansando? Isn’t ir usually to go?
