pi - regroups modifiers
ijo is the most generic word. it can stand in as a placeholder for anything or anyone.
pi is a really useful particle that regroups modifiers.
normally, each modifier modifies the sum of all the previous words in the phrase. the particle pi creates a second phrase which modifies the first phrase.
ijo pona mute
~ many good things
ijo pi pona mute
~ very good thing
in the first example, mute modifies ijo pona, while in the second example, pona mute modifies ijo.
when i say phrase, i mean a collection of a main word + modifiers, like jan or ilo moku.
it's a common mistake to try to cram as much information as possible into just one phrase. try to avoid this!
if you want to be more easily understood, it's often better to describe concepts in sentences, and then refer back to previously described concepts with a concise phrase which makes sense within the context you've established.
mi toki e ijo pi pona mute
~ i talk about a very good thing
mi toki e ijo pona mute
~ i talk about many good things
mi toki e ijo mute pi pona mute
~ i talk about many things which are very good
