Editing Tongue twister (section)

=== Fortis and lenis ===
[[Fortis and lenis]] are the classification of strong and weak consonants.

Some characteristics of strong consonants include:<ref name=":02"/>
* high frequency in a language
* earlier development in language acquisition
* lower placement on the [[phonological hierarchy]]

It is common for more difficult sounds to be replaced with strong consonants in tongue twisters.<ref name=":02" /> This is partially determinant of which sounds are most likely to transform to other sounds with linguistic confusion.
