Hi Raúl, "I began to learn English..." isn't a complete sentence and is actually a little unnatural in its structure. You should continue the sentence with when you actually started learning English. "I began learning English (when I was)..." or "I started learning English (when I was)..." would be better ways of structuring the sentence. E.g. I started learning English when I was in the University. I started learning English at a summer camp in school. Update 1: As Angela has mentioned, "I began to learn English" or "I began learning English" can be complete sentences as well. However, since you've asked about how you could use these sentences, I would say that adding a little context to these stand-alone sentences would make them more 'complete'. For example, the above would be perfectly fine as a sentence if it were a reply to a question: A: What did you do during your summer holidays? B: I began learning English. Update 2: Vivian's reply below works as well! Hope this makes sense! All the best in learning English!

i began to learn english significa : yo empece a aprender ingles. la oracion es correcta y completa. Si te preguntaran que idioma empezaste a aprender o que lengua estas aprendiendo esa seria la respuesta. por ejemplo: what language did you start to learn? ( que lengua empezaste a aprender ) i began to learn english

I disagree with some of the above, "I began to learn English" is a complete sentence. However, I would more likely say "I began learning English."
