How to use parallel
Parallel is used both literally (describing geometric lines or surfaces that maintain constant distance) and figuratively (describing similar situations, developments, or comparisons). In informal speech, it often appears in the phrase 'draw a parallel between' meaning to identify a similarity. The noun form is less common than the adjective and typically refers to a comparable person or thing, or in geography, a line of latitude.

A common mistake
Learners sometimes confuse parallel with perpendicular or use it to mean 'intersecting at some point'; remember that parallel lines never meet. Also, the spelling is often misspelled as 'paralell'.
