How to use conjunctions

Parts of a sentence are called ‘clauses’.

In short sentences (1 clause) there is no conjunction.

I like popcorn. I don’t like ice cream.

In longer sentences (2+ clauses) conjunctions can connect clauses.

I go to school and piano class on Mondays.
I like popcorn, but I don’t like ice cream.

Note: when writing ,(commas) are often used between sentence parts.
