# Group Similar Spellings

> Group together similarly written words that may be spelled inconsistently

This transformation is useful when, for example, you have freeform text in a survey,
where people will refer to the same concept in many different ways.
This helps clean and tidy your data by providing a consistent representation of each concept.

  Check out the
  [merge\_similar\_spellings](/api-docs/prepare/transform/merge_similar_spellings)
  step for more information.

## Parameters

* **Column**: the column to search and group terms in
* **Strength threshold**: a factor in the $[0, 1]$ range to make the algorithm more or less sensitive. A value of 1 will merge all ocurrences, while a value closer to 0 will search for stronger correlation between the terms, thus being much more strict with the merging.
