General English words
Certain English words (usually adjectives) are overused by learners of English. Word like: good, bad, nice, happy ….. are usually general ie they don’t express speaker’s/writer's ideas precisely or specifically. In addition, a text containing many of such general words is boring and leaves no room for imagination. Just imagine you read a book and the writer cannot vary his/her vocabulary, would you continue reading it? For instance instead of saying happy you can say: I was basically content, pleased, delighted overjoyed, or ecstatic as if putting them on a scale of varying degrees in descending or ascending order like adverbs of frequency. A very useful exercise or game for students of English is to avoid using such words. Students try to find a substitute and if they forget or can’t find an alternative somebody else continues the game.

Using very few overused or general words might make a text a bit more difficult but certainly more natural, lively and appropriate in particular situations. Little extra information evokes a positive feeling. Using descriptive words powers or tickles reader`s imagination. consider using other words that would better suit the context such as kind, generous, pleasant, tasty, lovely, scenic, colourful. On the other hand verbs like do, make, have, get.. can be more natural if they are used as part of informal register (phrasal verbs - Germanic English) instead of more formal words of formal register (Romance English) like receive, abandon, surrender....Words of Romance origin are often long ie multi-syllabic. Formal and informal register should always be considered depending upon the social context.

Learning the specific meanings and use of words, developing highly detailed vocabulary, is probably one of the more challenging aspects in learning a new language.. I am sure you will benefit quite a bit from such an exercise. Your thesaurus can become a good friend. Remember variety is the spice of life and feelings are neither good nor bad. You can increase or decrease the degree or force of your adjectives to comply with your mood and needs.The following is a list of some of such general words in alphabetical order and suggestions for using more specific words:
