Des caractères adjacents sont inversés.

Transposition errors occur when two adjacent characters swap positions. This is one of the most common data entry errors, often caused by typing too quickly or by dyslexia. Examples include typing '1324' instead of '1234' or 'hte' instead of 'the'. These errors are subtle because all the correct characters are present.

Original: ABCD → Error: ABDC (C and D swapped)

12345 → 12435 (3 and 4 transposed)
ABCDEF → ABDCEF (C and D transposed)
AB-1234 → AB-1324 (2 and 3 transposed)

Comment le reconnaître

Same characters, but two adjacent ones are in reversed order
Length remains the same
Often occurs in the middle of strings
