hello..i would like to ask you how to use the bombastic words when we need to elaborate our composition...
Hahaha....the short answer is that I would not use "bombastic" (meaning pompous) words in a composition. They don't make your writing more interesting. Often your readership doesn't understand their meaning. Using such words gives the writing a pompous, arrogant, conceited tone which should be avoided.
A lot depends on the culture you are writing in. In western countries, using long and obscure words is, as Naamplao says, best avoided. But in some other cultures, using such words shows respect and formality, rather like taking extra care to dress smartly when preparing for dinner with the Ambassador.
