lun
lun is a particle that turns words into a verb meaning "to <word>-ify X" or "to make X into <word>".
Use
Now, importantly, whether the word is interpreted as a modifier or a noun is important to the meaning. For example, if in lun tope, tope is intepreted as a noun, then lun tope would mean "to make into goodness", not "to make good". Simiarly, if in lun nin, nin is intepreted as a modifier, then lun nin wouldn't mean "to make into a person", it would mean "to make similar to a person".
One is making the object like the word, whereas the other is making the object be the word. Whether lun is using its modifier meaning or its noun meaning is dependent on context, and on the argument it's taking in.
If a noun is passed as the argument for lun, so for example, lun nin, the default lean is that lun is using its noun meaning. This would mean that defaultly, lun nin means "to make into a person", not "to make similar to a person".
The same goes for modifiers. Defaulty, lun tope means "to make good", not "to make into goodness".
However, this is dependent on context, and can be specified if you want to mean something that is not lun's default lean.
To specify that you're using lun's noun meaning, you can add wen before the argument. So to specify that you're trying to mean "to make into goodness", you could say lun wen tope.
Simiarly, to specify that you're using lun's modifier meaning, you can add wi before the argument. So to specify that you're trying to mean "to make similar to a person", you could say lun wi nin.
And lastly, it should be noted that this verb, isn't really grammatically a verb. It makes more sense to think of it as a verb, however it cannot be used when not in front of le or o. For example, the sentence lun tope le tope would be ungrammatical.
