Phonotactics: Difference between revisions

[[Toki Pona]]'s '''{{wp|phonotactics}}''', orthat is the rules for putting sounds together, are well defined. Unlike its [[phonology]], knowing the phonotactics is not needed to speak the language orally, since the main set of words already adheres to them. It is most useful for creating [[name]]s and {{tp|[[nimi sin]]}}. An asterisk marks a sequence that is not allowed phonotactically.

In itsthe lesson "Proper Names" lesson, {{pu}} lists the phonotactic rules of Toki Pona in the following order.:

* '''No adjacent nasals.''' {{Indent|In sequences like {{tp|*anna}} and {{tp|*anma}}, the first syllable's coda {{tp|-n}} would {{wp|Assimilation (phonology)|assimilate}} to the second syllable's onset nasal: respectively {{tp|ana}} and {{tp|ama}}.<ref group="lower-alpha">Assimilation of coda {{tp|-n}} is also responsible for words like {{tp|anpa}} sometimes being pronounced like {{IPA|[ampa]}}, and words like {{tp|enko}} (an obscure {{tp|nimi sin}}) being pronounced like {{IPA|[eŋko]}}.<br />As a result, coda {{tp|-n}} is sometimes defined as {{IPA|[m ~ n ~ ŋ]}}, unlike onset {{tp|n-}} which is strictly {{IPA|[n]}}.</ref>}}

===Palatalization===

The syllable {{tp|*ti}} is disallowed because of {{wp|Palatalization (sound change)|palatalization}}, a common sound shiftchange that has occurred in many languages. An English example is the suffix "-tion", as in "motion". The previous phonemes {{IPA|/ti/}} hashave been palatalized to {{IPA|/ʃ/}}, so it sounds like "-sion" as in "mission". For the same reason, {{tp|*ti}} is changed to {{tp|si}}.

BecauseAs the phoneme {{IPA|/k/}} can also be palatalized<ref group="lower-alpha">This is why the letter C, originally {{IPA|/k/}}, now has soft and hard sounds.</ref>, many languages merge {{IPA|[ki ti si]}}. There are no minimal pairs between {{tp|ki&ndash;si}} minimaland pairs{{tp|si}} in the 120 {{tp|[[nimi pu]]}}, and among all [[ijo Linku#Word usage surveys|commonly used words]], onlyexcept for the word {{tp|kin}} can be mistaken for {{tp|sin}}.

'''{{tp|wuwojiti}}''' is a {{w|mnemonic}} word for the disallowed syllables in [[Toki Pona]] phonotactics: {{tp|*wu}}, {{tp|*wo}}, {{tp|*ji}}, {{tp|*ti}}, and their equivalents with coda {{tp|-n}}nasal. Some less commonuncommon {{tp|nimi sin}} flout this rule, often as a joke.
