The Portuguese Stress Lexicon (PSL) contains non-verbs in the Portuguese language (excluding monosyllables). The lexicon is largely based on the list of words in the Houaiss Dictionary (Houaiss et al. 2001), which is the most comprehensive dictionary in Portuguese. PSL contains 154,610 entries and 62 columns, which provide a comprehensive set of variables (including pronunciation, syllabification, stress position, syllabic constituents, intervals, CV profiles and weight profiles).


The lexicon was developed as part of Garcia (2017), which examined weight and stress in Portuguese. Because stress in verbs is not phonologically conditioned in the language, only non-verbs are included in PSL.

A note on nasality

The symbol used to represent nasalization is the tilde (~). This is treated as a coda consonant in the lexicon (except for ão sequences, see below). For example, in the word anã (‘dwarf’, fem.), transcribed as a.'na~, there is a word-final coda, namely, ~. In cases where nasalization is the result of assimilation, ~ is not used. For example, the words cama and canta (‘bed’, ‘sings’), are transcribed as ' and 'kan.ta, respectively. Finally, in words with ão, the tilde is assumed to be in the nucleus. The word coração (‘heart’) is transcribed as ko.ra.'sa~w. The assumption that nasals in Portuguese are VN sequences is based on Mattoso (1969), and is not definitive. Rather, this should be taken as a (neutral) baseline for the general characterization of the Portuguese lexicon.
