RE: Source(s) - Primary, on through Secondary: Part 1: no-ledge, schooled ("What's up, Docs?") 

"Go to!" The source(s) of course, what did you think I meant?! Back in our days, of growing up, in the 'age of innocence😁😂😉' all we had to say, when we wanted to "tell someone off!" was just utter a few words, give them a glimpse of what we meant, a "tacit indication" of "where to go!" Yes, tacitly stated...

"You know what I mean" Perhaps in only a few words, we "implicitly" state, contrasted with "explicit, formal, codified...knowledge that is more difficult to transfer by others by means of writing it down or verbalizing it..."...without actually saying, not even having to say so, even by "remaining silent on the subject"...in a way that is partly unconscious😔😕 or cannot be expressed adequately through ("use your words")...If you do this a lot, of course, you could become known as a "man of few words"...Which, while still "short on words", is different, at least in quality than someone referred to as "laconic" ("succinct, pithy, concise..."). Yes, tacit expressions, sometimes in the context, intention on being subtle, tactful, delicate, or others to be coy...truncate in attempt to obfuscate...the "truth of the matter..." Which may, upon further investigation, turn out to be something quite different than, the...

"Original" What we were told to be by lots of adults growing up: "be different, an individual thinker, a real original..." Which, depending on just how far we took it, might be followed by, qualified, tempered with "Up to a point, that's not quite what I meant..." And which, especially inside the school setting, became coupled with, in tandem with "Go to" and became "codified" into part of our "academic freedoms" Well, actually in showing a bit of re:straint, as in having to show the degree to which we cited original, which other-wise became known to us as "primary" versus "secondary"...sources of info., knowledge...Not only to obtain a good grade after handing in the paper of the subject du jour, and not just to make it through the primary and secondary grades, on to the places of "higher knowledge" about which we heard so many rumors, fanci-full stories, promises of riches if we just work hard, acquire enough knowledge, etc. etc. etc....blah, blah, blah...

"Don't go there" As in avoid the dread-full, or where "no one has gone before" or "best re-main unspoken" Another implicit, indication of where we might not want to test the limits, go "out on a ledge", play "loose with the truth". During our more formal school daze, we learned the value of citing, re-citing our sources, sometimes even by "footnotes" (ancillary piece of info...'marginal notes'...explications) that, sometimes as an afterthought, perhaps prompted by our parents ("you better...") struggled, sweated, "burned the midnight oil" trying to figure out how to fit them onto the bottom of the page, or the margins, nicely de-lineated for us, "back in the day", as we tried to fit all this onto one page, before our teacher got hold of it, well before the days of "word processing" the days, the times when we were first introduced to "white out" first in fluid, then more neatly, via tape, and eventually became, around this geo. region, as a reason to cancel school (you know, before the days that "asynchronous instruction" was even dreamed of) and, if you were lucky enough to get to one of those "institutions of higher learning" might even, depending on your school colors, become a form of association, fellowship, even a way to get on national TV, waving a towel, yelling whatever cheer you were told to do in concert with the throng of well-wishers, hoping your folks had tuned in to see you "root, root, root, for the home team...!" So they could see how well you were using that in-tuition, that they imparted, de-parted with, while they, your parents, who were probably a good portion of the $ource(s) -- of both your knowledge and financial backing -- were relegated to (literally) the sidelines, to "sit back and watch this all un-fold". And, of course, another source, your teachers, who are probably looking on at the moment as well, the ones that stayed up late at night to correct all those papers, spent many waking hours, sleepless nights, trying to...

"Root out" Get to the source of it -- here, meaning trying to trace your sources, the paper trail, to see if you really bothered to...go beyond the "Encyclopedia Britannica" in our days which, of course, has been usurped, re-placed, supplanted by "Wiki"-everything...Yep, they stayed up late while we "slept like babies" Sort of a "cat and mouse" game we played all the way through our formative educational experience, prior to entering, the "hallowed halls" of ...? Which, instead, if we didn't follow the "rubric" close enough, the small print on the syllabus, or bothered to study the code of student conduct "copiously" could, instead find ourselves being accused, if not found guilty of "...academic 'dis'-honesty...being a copy-cat, cheater..plagiarist...or, the most dreadful four-letter word in our earlier vocabs, at least: 

L-A-Z-Y!😝😡😘
