Synonyms are words with the same meaning. They are the opposite of antonyms.

pu "synonyms"

pu lists the following 3 words as "synonyms", not counted among the 120 nimi pu:

Word Definition in practice "Synonym" Merged definition
kin also a emotion particle, emphasis marker
namako spice, extra sin new, extra
oko eye lukin see, eye, (pre-verb) try

Those words have been in use before and since the publication of pu, but with different meanings from their supposed relatives. Calling them "synonyms" was a deliberate attempt to merge them.[1] ku acknowledges that the words have retained their separate meanings among those who use them.

The merger of these words was mostly successful with lukin/oko, and mostly unsuccessful with sin/namako and a/kin. However, kin's original role as an emphasis marker moved completely to a, which was previously only a sentence-final particle to indicate emotion.[2] Here is an overview of how meanings changed over time:

Word Pre-pu usage Usage in pu Post-pu usage
a emotion particle emotion particle, emphasis marker emotion particle, emphasis marker
kin also, (uncommon: emphasis marker) also
sin new, another, more new, another, more, extra, additional new, another, more
namako spice, embellishment, extra, additional spice, embellishment, extra, additional
lukin see, look, visual see, look, visual, eye, try see, look, visual, eye, try
oko eye eye, (uncommon: see, look)

ali

ali is generally considered a pronunciation variant of ale, rather than a separate, synonymous word.
