Learn Hardcore Spanish (Latin America): Practico la pronunciación en español todos los días. - I practice pronunciation in Spanish every day.

In this sentence, practico is the first-person singular present tense form of the verb practicar (yo practico), which has no written accent. If you see práctico with an accent in another context, it usually means "practical" as an adjective, not "I practice."

Is there any difference between saying Practico la pronunciación and Practico pronunciación without "la"?

You can say both. Using la emphasizes "the pronunciation" in a more specific sense, while dropping it sounds slightly more general. However, in many cases, native speakers will use la to refer to the concept more naturally.

Why do we say en español instead of en el español?

When referring to a language in Spanish, we often just say en español, en inglés, etc., without the definite article. It's a standard usage, so en el español would sound awkward unless you have a specific context that needs the article.

How do I pronounce todos los días?

Break it down as to-dos (with a clear "o" sound) lohs (the "s" is a soft "s"), and dee-as (the "í" in días sounds like "ee," and the final "s" is again the soft "s"). Make sure to keep the stress on the first syllable of días.
