Hi there,
I decided to put this here in the linguistic section because it seems like a strange and very complicated subject to discuss.
I am going to improve my vocabulary in a systematic way (finally!), using a technique I don't feel like discussing right now. The goal is moving from a basic vocabulary (believe, sadness, smart) to a more advanced one (elicit, mourning, gullible... and assorted phrasal verbs, sayings, and idioms).
When I come across a new word, the only thing I can do is look it up in a dictionary. Two dictionaries, to be precise (Longman + M-Webster), and sometimes even three. What I have noticed is that as soon as you are interested in more advanced vocabulary, learner's dictionaries become more and more limiting and imprecise, and dictionaries for native speakers like Merriam Webster become indispensable. In any case, it seems I am now faced with the daunting task of understanding something along the lines of...
- What's the difference between sly, cunning, wily, slick, guileful, etc.?
- What's the difference between moan and groan?
- What's the difference between gleam, glint, glisten, glitter, glimmer and shimmer?
- What is the exact meaning of facetious and what does it imply?
And so on, those were just a few examples.
Now, one solution might be: open a thread and ask. Hmm, how would you like a hundred threads of mine per month, often on pretty trivial differences?

Hehe. That would bring up a problem, which I am actually interested in: do you think all native speakers feel the same difference between a certain set of synonyms? Do you think all of them actually know the real meaning of certain words?
The next solution, the only feasible thing to do, seems to look up each word in a couple of dictionaries and try to understand the general meaning, always linking the meaning with a clear example. Easy? Not really, especially when two definitions you got from two different dictionaries don't seem correspond completely. One definition might be too broad, the other too specific and only limited to one case. Let's give a couple of examples:
GrimaceLongman: (verb) to twist your face in an ugly way because you do not like something, because you are feeling pain, or because you are trying to be funny - (noun) an expression you make by twisting your face because you do not like something or because you are feeling pain
Webster: (noun) a facial expression usually of disgust, disapproval, or pain - (verb) no definition, but it's listed, so the meaning is related.Comment: From Longman, I get it has a pretty general meaning, exactly like the Italian word "smorfia". On the other hand, Webster does not mention positive qualities, even though it says it's "usually" related to disgust, disapproval, or pain. Making ugly faces just for fun might be included, but it makes it sound like it's a generalization and not really the main meaning.
Groan (verb, person uttering a sound)Longman: to make a long deep sound because you are in pain, upset, or disappointed, or because something is very enjoyable
Webster: to utter a deep moan indicative of pain, grief, or annoyanceComment: Longman includes groaning because of pleasure, but Webster does not mention anyhting positive or enjoyable, not even under "moan". Both of them don't seem to make any difference whatsoever between "groan" and "moan", although Longman explicitely mentions "sexual pleasure" under "moan" instead of generally referring to an enjoyable activity.
Just some examples. In most cases it is possible to get the general meaning and "feel" some implications and differences there might be, but other times it's even difficult to be sure of the main meaning. Up to now, I have always thought of "moan" as the more general term, and "groan" as the one more related to bad feelings and suffering, but when you look up those words you can't help but say "What the hell?"
Sorry if this was too long, but if you feel like replying, just comment on whatever you want. I just need to hear some advice that will help me understand more about these problems, so that I will be able to make the best decisions and improve my English as much as it's theoretically possible. Thanks.
