Introduction
Learning Spanish actually significantly will improve your understanding of English. If you are native English speaker and had solid grammar before learning Spanish, but this was more through osmosis. framework for that, and you will be better able to explain to people learning English why we say things the way we say them, so your grasp of English is also stronger because you’ve studied Spanish. It depends. If you are a native speaker of English, it seems unlikely that it would do anything other than help your grasp of English. If you are also learning English, it’s possible that along the way, there would be some interference and you might confuse patterns in Spanish with patterns in English.
You will find that learning Spanish and other languages will increase your competency in understanding English, particularly because you have to understand how Spanish works, and you can see how it’s different from English. It gives you a deeper appreciation and understanding to work from.
For example, in English we tend to use gerunds and the -ing form of verbs a lot, yet we don’t have much of a subjunctive or conditional mood to work with, so you’ve had to understand why that is in English and be able to understand the deeper meanings of phrases in English when you need to translate to Spanish, which tends to use the infinitive more, and contains a full subjunctive mood in several tenses.
However, sometimes you have to struggle to find a word that you want in English, or it takes me a bit longer to recall. I think this might be a trade-off occasionally for knowing more language–you have a larger register of knowledge to work from, so your brain spends a little longer running through the linguistics of what you’re trying to say.
