The word 'parallel' can be used to describe two things that are similar and happen at the same time. For example, train tracks run parallel to each other because they run in the same direction and never meet. Lines on a piece of paper can also be parallel if they are the same distance apart and never cross. We can also use the word parallel to describe two stories, events or situations that are happening at the same time but do not directly affect each other.
