Best Pali to English translation source

I’m very new to Buddhism and am wanting to find an accurate source to show me the word-for-word interpretations of terms and words. Right now I’m trying to learn the meaning of each word of the “Ethan santhan ethan paneethan..” chant and although I have the English explanation of the whole thing, I want to know what each word translates to in order to gain the best personal understanding of how this mantra is said and also how Pali works. I’d appreciate any help on this. Thank you.
