user16421: 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.

user10100: You have to memorize the whole Pali context, not only "etam santam etam panitam" part, the answer is inside the entire Sutta's skeleton already. 
Start with clinging in 5 string aggregates, which is sankhara (unpeaceful; asantam) 
>>
More and more peaceful by clinging in only 1st jhana-8th jhana aggregates, which has lesser sankhara, but it still has  (unpeaceful; asantam).
>>
The most peaceful (peaceful; santam) is sabba-sankhara-vupasamatho.
For how is it unpeaceful, see MN Mahadukkhakkhandhasutta.

So other answers have already mentioned SuttaCentral.
There's also a Digital Pali Reader which I haven't tried (but which other people have, and liked).
And some of the suttas on buddha-vacana.org have "word by word" translations (i.e. if you use a mouse to hover over a word).
As for "how Pali works" I guess you need to ...

Know vocabulary (e.g. via dictionaries, of which there are several, and/or by looking at words in context, and/or seeing how other people translate them)
Know that words are compounded (aggregated into longer words, a bit like in German), however they're compounded in different ways (see here and/or here) -- you might need to guess at how to break a compound word into its components and look up each word separately.
Nouns are declined and verbs are conjugated (like in Latin or Greek)

You can't afford to ignore declension. In a Pali sentence like "man dog bites" then the nouns "man" and "dog" would be declined to show which is the subject or agent in the sentence, i.e. to show whether it's saying "man bites dog" or "dog bites man" -- it's the declension not the word order that's important (and declensions might be instead of prepositions too).

This list -- Declension of Nouns -- helps to look up the declension of nouns. See also the Pali Toolbox more generally.
The Syntax of the Cases in the Pali Nikayas tries to explain what each declension means -- e.g. "what might it mean when a noun is in the 'ablative' case?"

Questions about Pali itself (i.e. questions about the language) aren't really on-topic on this site, though, though questions about the meaning of specific Buddhist doctrine written in Pali is on topic.

user16297: Here is a slightly modified B.Thanissaro translation of that passage (etam santam...), with pali + english lined up side by side, nearly word for word order.
http://lucid24.org/an/an09/an09-0036/toc-addon/index.html
suttacentral.net is an excellent resource, if you configure the settings on there to show pali with english for B.Sujato translations (aside from KN, he has complete set of translations for nikayas). You can view them side by side or line by line.
lucid24.org has a snapshot of B.Sujato's translations as of 2019-jan., arranged in side by side pali+english, with an important correction to B. Sujato's mistranslation of the 4 jhana formula. 
DPR (digital pali reader) is an offline excellent resource addon for firefox.
Those resources will save you an enormous amount of time from the tedious and frustrating old tech research methods. But with that said, don't expect to get an understanding of the Dhamma even if you read the entire Pali and English collection with a decent intellectual understanding. It's only through repeated reflection over years, and seeing how the various important terms are used in various contexts throughout the canon, and a deepening of samadhi in your meditation practice that the passages will really make sense, and you're able to sort out for yourself the various controversies and sharply divergent interpretations existing out there.
