Description:

The term 'pue' refers to feelings or emotions, and in its verbal form is an important copular verb.

Verb:

As a verb, 'pue' is an intransitive pali verb that takes an absolutive being that feels. It is often used with an adverb that described the emotion, but it can also take a argument in the nominative case introduced with the null preposition that is the thing felt. It can be used in a causative form where an ergative causer of the feeling is added.

The general copula 'an' can also be used for feelings. The difference is that 'pue' describes the feelings as more intense, transient and in the moment, whereas 'an' describes the feeling as more general, long-term or of lower intensity as an overall average state.

The derived form 'upúe' has the sense of 'care', in a general sense of caring emotionally, not necessarily in the sense of providing care or help. To get the sense of 'care about (something), use 'pue' and introduce the thing cared about with the proposition 'u'. This expression is generally positive but doesn't have quite the positive connotation that the English equivalent does, it can refer to antipathy, it is just a statement of having feelings invested in something. Positively can be made explicit with 'zra' as an adverb 

Noun:

As a noun, 'pue' refers to a feeling or emotion. The derived form 'puesyn' means 'mood', including grammatical mood as a calque of English.

Modifier:

The modifier form 'pues' has the sense of 'with feeling' and conveys senses like strongly or adamantly.
