What do you call the method what you use when you know what to say but not exactly how to say it but use another method to do so?
You have an idea you have to explain to people, you know what you want to say but not how to articulate it correctly. So you end up using examples, sayings to help the person to understand what you are trying to convey, to help to get to the meat/jist of it until you get an "aha"moment that is what I'm trying to say
The stackexchange english language user knew what he wanted to ask in an indirect way but didn't know the exact words to ask it correctly so he used examples to trying get the question in a "roundabout" way.
Pete wants directions to the arcade. He asks a passerby but forgot the word " arcade" so instead he asks "can you give me directions to the place in the mall where the 12-year old kids hang out?" He used workaround way to explain where he wanted to go. He didn't say the correct word but the passerby knew the place he meant.
What method did Pete use?
For the above Pete can't explain the word succinctly so he uses a [...] way or expresses it 
Words that don't fit exactly:
convoluted means. Convoluted means difficult to understand or complex where I'm trying to instead convey it's an "other" way to ask to get there.
non-succinct way also is similar to the above
Inarticulate method coveys he isn't clear which is untrue since he is using another method
parallel conveys the two ways that are the same, where instead I want to say the the other method is instead an out of the norm way
Roundabout,Workaround is probably the closest I can think of
This might be a better explanation of the context
The computer system user asks a question but the support ticket was closed with explanation "Your question is convoluted". The user believes the reason is unfair as he believed he question in isolation might be phrased without the correct technical terms but he additionally used a specific example to explain what he was trying to achieve which left no room for ambiguity to understand what he was asking. He escalates it to their manager saying his question was not convoluted as he used used a [got to the jist of it] way to explain which the helpdesk should have understood and that he feels they were intentionally being pedantic.
