I want to know about neither structure and correct usage of it. i also want to its condition in grammar.
And i will very thankful you if you sent me interseting vocablorary please.
Many commercial EFL web-sites have a 'word of the day' feature. Try Macmillan Educational.
Incidentally, do you really mean 'neither'? It's either 'both... and' or (its opposite) 'neither ...nor'. Some dialects are happy with 'neither ... or' (I suspect their prescriptivist grammarians got over-excited at the whiff of a double negative, and the prescription passed over into regular usage!). Anyway, whichever you mean, it's not 'neither ...and'.
