pi 之
sep of, belonging to
→ pi orders a string of modifiers that could be interpreted in more than one way.
moku tomo sona - ?smartly home prepared meal
moku pi tomo sona - school lunch (pi separates the compound tomo sona ‘school’)
tomo telo nasa - ?the crazy toilet (tomo telo as a compound reads as ‘toilet)
tomo pi telo nasa - a bar (pi separates telo nasa, ‘alcoholic drinks’).
→ Other examples
jan pi ma tomo - person of the city, a city-dweller
kulupu pi toki pona - group of Toki Pona, the Toki Pona community
nasin pi toki pona - ways of Toki Pona, the ideology behind Toki Pona
jan lawa pi jan utala - leader of soldiers, a commander or general
jan lawa pi tomo tawa kon - leader of airplanes, a pilot
jan pi pona lukin - person of visual goodness, an attractive person
jan pi ike lukin - person of visual badness, an ugly person
→ the personal pronoun mi, sina, ona, function also as possessive pronouns when placed after a noun. That doesn’t work for names. Using pi can clarify things here also.
kili mi - my fruit
kili jan Susan - ?Susan fruit
kili pi jan Susan - Susan’s fruit
→ More examples
ma ona - her country
ma pi jan Keli - Keli’s country
len jan - somebody’s clothes
len pi jan Lisa - Lisa’s clothes
→ Using pi with the plural pronouns like mi mute ‘we’ and ona mute ‘they’
nimi pi mi mute - our names
tomo pi ona mute - their houses
NB according to wikibooks.org, pi is required with plural pronouns
→ Special usage of pi to express the opposite of some words
jan wawa - a strong person
jan pi wawa ala - a person of no strength; a weak person
NB wikibooks.org suggests that pi can make a big difference: jan wawa ala ‘no strong person; no strong people’ versus jan pi wawa ala ‘person of no strength’ .
→ You can use pi to separate compounds to express ‘about; with regard to’
mi toki pi jan ike - I talk(ed) about bad people
compare: mi toki jan ike - ?I talk(ed) humanly evil (or something like that)
NB wikibooks.org claims that one should only use pi in instances where it usefully separates compound words. wikibooks.org disapproves of mi toki pi jan (I talked about people) because mi toki jan would already be clear enough. However, apparently quite a few Toki pona speakers seem to use pi like that.
→ You can use pi to express possession more explicitly: pi mi ‘mine’, pi sina ‘yours’, etc.
kili ni li pi mi - this fruit is mine
tomo ni li pi jan Tom - that house is Tom’s
ilo ni li pi sina - this tool is yours
toki ni li pi mi mute - this language is ours
→ Possible errors using pi
Simple compounds like jan lawa ‘leader’ or jan ma ‘a countryman’ don’t require pi. The author of wikibooks.org claims that pi should only be used in case a string of modifiers needs clarification.
A more obvious error is using pi instead of tan (in the meaning of ‘from’).
mi kama tan ma America- I come from America
