Language use

The easiest way to check your language use is to use a GOOD dictionary (Macmillan, Oxford, Cambridge, Longman). A good grammar reference book is also extremely useful. In general, uncommon words are much harder to use appropriately. A quick and easy way to check if your usage is commonly understood is to check a corpus, such as the British National Corpus.

Uncommon words may also be stylistically undesirable. It's best to aim for a more elegant and direct style, and pare down overblown imagery, unnecessary similes/analogies/metaphors, hyperboles, clichés and redundant words. Reconsider the use of '$10 words'; edit ruthlessly and 'murder your darlings'.
