Phonological word
{{Technical|date=May 2015}}
The phonological word or prosodic word (also called pword, PrWd; symbolised as ω) is a constituent in the phonological hierarchy. It is higher than the syllable and the foot but lower than intonational phrase and the phonological phrase. It is largely held {{Cite book |last=Hall |first=Tracy Alan |url=https://benjamins.com/catalog/cilt.174.02hal |title=A Review: The Phonological Word |date=1999-06-15 |publisher=John Benjamins Publishing Company |isbn=978-90-272-3680-7 |editor-last=Hall |editor-first=Tracy Alan |series=Current Issues in Linguistic Theory |language=en |doi=10.1075/cilt.174.02hal |editor-last2=Kleinhenz |editor-first2=Ursula}} to be a prosodic domain in which phonological features within the same lexeme may spread from one morph to another, from one clitic to a clitic host, or from one clitic host to a clitic.
The phonological word and grammatical word are non-isomorphic.{{Citation |last=Nespor |first=Marina |title=Prosodic Phonology: With a New Foreword |date=2012-03-12 |url=https://www.degruyter.com/document/doi/10.1515/9783110977790/html |work=Prosodic Phonology |access-date=2023-04-28 |publisher=De Gruyter Mouton |language=en |doi=10.1515/9783110977790 |isbn=978-3-11-097779-0 |last2=Vogel |first2=Irene}} Sometimes what counts as a word for the phonology can be either smaller or larger than what counts as a word for syntactic purposes. A clear case of this mismatch is compound words, which count as two words phonologically, but one in the syntax.{{Cite book |last=Zsiga |first=Elizabeth C. |url=https://www.worldcat.org/oclc/799024997 |title=The sounds of language : an introduction to phonetics and phonology |date=2013 |isbn=978-1-4051-9103-6 |location=Chichester, West Sussex, UK |oclc=799024997}}
