Favourite and disliked words

Firstly I would like to talk about my favourite and disliked words which I use or can't stand using on a daily basis. As we all know English as any other language consists of a wide range of different types of words. Some people may use some words more often than the others. For instance it is more likely that teenagers will use slang words on a daily basis rather than using formal types of words.
However we all have our favourite words and also those which we dislike.
Personally I love using different types of adjectives, no matter whether it's in a speech or a piece of writing I just think they make the piece much better and more professional. Adjectives such as 'incredible', 'thrilled' or 'mysterious' are some of my favourites due to the effect that they give to a piece of writing and the emotions that they put on a reader. Other words which I use quite frequently and really like using are 'however, therefore, despite' etc. These conjunctive adverbs make any piece more complex and allow the writer express their view or opinion in more detail.
There is way more words which I like and use very often but it would take me years to talk about them all, therefore now I will mention a few words which I don't like and don't use too often or not at all.Some of these words are slang words used by a large number of teenagers nowadays such as 'bae', 'dodgy' or 'dope'. There are also adjectives like 'lovely' which I cannot stand. The reason for it is that most people nowadays use this adjective to describe almost everything. It makes me feel that it's not as unique and it doesn't sound as nice as other adjectives which can easily be found in the dictionary.

The second subject of this post are my own uses of language. What I mean by 'my own uses of language' is the type of language I use when I speak to my friends, teachers or strangers, when I use formal language and why I use it.
When speaking to my friends I usually use quite simple English, sometimes I might also use some slang phrases. This is because I interact with teenagers and I know this is the language they speak too, if I suddenly started using a formal language I think they would be quite surprised and possibly laugh at me. However when I speak to teachers or other adults I try to use more complex, sophisticated language as I know the language I use presents the person I am, for instance when an adult speaks to a teenager who constantly uses slang words they might think that they have a limited range of vocabulary or knowledge. I only use formal language when I write letters, emails to adults or when I take part in any kind of interview.
