Embellish – (verb) – to decorate (something) by adding special details and features : to make (something) more appealing or attractive.
I came across this word while reading Quicksand by Nella Larsen (on page 37 at the bottom). This was the context, ” And then he had spoken of contentment, embellishing his words with scriptural quotations and pointing out them what it was their duty to be satisfied in the estate to which they had been called, hewer of wood and drawers of quarter”. In this case, the statement was given some extra details to make it seem more viable or more informative.
