Just enough theory to use it
English changes with the situation. The level of formality is called register, and choosing the right one is a competence aim in itself: your language must fit purpose, receiver and situation. Formal English avoids contractions, prefers precise single verbs over phrasal verbs, and uses academic vocabulary. Informal English is personal and direct, and works in dialogue and social media. Neither is «best» – a formal letter written in slang fails, but so does a text message written like a legal document. Strong students switch register on purpose and can explain the switch.
