Thank you.
one question, what does sepi'o mean or do in a bridi?
{se pi'o} is two words. Just {pi'o} is a tag which inserts the x1
place of {pilno} into a bridi. With {se} in front, you get a tag which inserts the x2 place. We can be more precise by actually using {pilno} as our main selbri and filling all three of its places:
.i ko pilno la .skaip. lo nu do tavla
Or we can be less precise by making a tanru:
.i ko pilno be la .skaip. [be'o] tavla
mi'e la latro'a mu'o (This means "my name is {latro'a}, my message is complete, you may respond.")
