在光标下询问单词，用于在vim中拼写突出显示

Question

I've recently discovered the built-in spell checking of Vim. I noticed in the documentation that there were several classes of highlighted words that are revealed by activating spell checking (a la :setlocal spell spelllang=en_us ). These different classes show me different kinds of spelling errors, but it's not always clear to me which kind of error I've made just based on the color.

I know that I can look at different spelling suggestions for the word using z= with my cursor over it, but I'd really like a similar command that just tells me what type of spelling error I've made.

I also know that I could look at the list of different highlighting classes using :hi , but that's rather unwieldy. I'd like to have a quick way of looking up the name of the class from the :hi table that is being applied to the text under the cursor.

The closest I've gotten is :echo synIDattr(synID(line("."),col("."),1),"name") , which gives me the syntactic context under the cursor. This doesn't actually tell me anything about spelling in any of the contexts I've tried.

I don't know a way to query the current word's type of spell error. Because I frequently forget which highlighting means what, I have defined this command to aid my memory:

function! s:SpellLegend()
    for [l:group, l:explanation] in [
    \   ['SpellBad', 'word not recognized'],
    \   ['SpellCap', 'word not capitalized'],
    \   ['SpellRare', 'rare word'],
    \   ['SpellLocal', 'wrong spelling for selected region']
    \]
        echo ''
        echon l:group . "\t"
        execute 'echohl' l:group
        echon 'xxx'
        echohl None
        echon "\t" . l:explanation
    endfor
endfunction
command! -bar SpellLegend call s:SpellLegend()
