Common mistake
Confusing them due to similar spelling. Wrong: "She sat besides me." when meaning physically next to. (correct: She sat beside me.)
Trick to remember it
'BesidE' (no final S) = physical position, next to. 'BesidesS' (with S) = in addition, furthermore. The extra 's' signals extra information.
Quick rule
Saying something is physically next to something? Use 'beside'. Adding information or saying 'in addition to'? Use 'besides'.
Did you know?
'Beside the point' means irrelevant or off-topic: 'That argument is beside the point.' And 'beside yourself' means overwhelmed with emotion: 'She was beside herself with joy.' Both fixed expressions use 'beside' (no S), not 'besides'.
