far / wide
'weit' and 'nah' both describe a distance, but they mean the opposite. You use 'weit' when the distance is large. You use 'nah' when the distance is small. The words can be confused because both often occur with places, routes, or appointments. Pay attention to the direction of the statement: 'nicht weit' (not far) means almost the same as 'nah'. 'nah' can also refer to time, for example a near upcoming appointment.
