# distanceBetweenString:andString:distanceType:

Calculates the distance between two strings in the vocabulary space.

## Declaration

```occ
- (NLDistance) distanceBetweenString:(NSString *) firstString andString:(NSString *) secondString distanceType:(NLDistanceType) distanceType;
```

## Parameters

- `firstString`: A string in the embedding vocabulary.
- `secondString`: Another string in the embedding vocabulary.
- `distanceType`: A means of calculating distance that determines which formula the method uses to evaluate the distance between firstString and secondString.
