There are pluses and minuses to translation.
As a woman who was brought up in an english speaking environment, my hebrew is ok. I can understand what a paragraph is talking about, but if you asked me to translate word for word, I’d have a problem. I appreciate the english translation in the siddur and tehillim. As well as the chumash – so that i can help my children to better understand what they are learning in school.
IMO, english translation in seforim are good for those that learn on their way to/from work/appts/etc and cannot just ask their chavrusah to help translate something.
