Sir: these two words/terms (Wanna & Gonna) are in spoken English frequently.
What does it mean? Kindly teach me in a detail form.
Have a good day.
"Wanna" is a contraction of "want to" and "gonna" is a contraction of "going to. They are very informal and not to be used in written English.
Note: always capitalise the first letter of countries, languages and nationalities.
