So, let’s embark on this linguistic journey that promises to refine your verbal and written interactions.
Formal Language is like a formal dress, in formal language you have to be careful with words, and you have to choose words with respect.
You cannot use the word ‘Ask’ in formal language because it is an informal word. You have to be a bit polite in formal language and vocabulary words, rather you can use ‘Inquire’ which is more formal than ‘ask’.
Informal Language is the language you speak with your friend’s circle. It is used in conversation with your family and friends, informal words are also respectful words, but they are less polite as compared to formal words.
Venturing into the linguistic landscape, we first encounter common words that wear formal and informal hats. This section unveils these versatile words, easing your journey across professional and casual dialogues.
