Description:

The modifier 'sawy' means 'thirsty' and also describes being low on something, especially energy or fuel, as in a low battery, or an almost-empty fuel tank.

Modifier:

As a modifier, 'sawy' means thirsty, or low on something, typically some kind of somewhat abstract essence like electricity (in a battery) or fuel. The usual expression for to be thirsty is much like English, to attach the modifier 'sawy' to a subject via the copula 'an'.

Verb:

'Sawyn' has be used directly as a verb meaning to thirst - as such it is an semitransitive noxaj verb taking an absolutive one who thirsts and a dative thing thirsted for. In this sense it can be used to mean literal thirst, but can also be generically extended to a word for any sort of primal and essential desire. This sense can be sexual, but doesn't automatically have that connotation. For example, the expression:

We nox sawyn ija ysáz zun.
I(ABS) go(NP.IM) thirsty-TER the(DAT) blood you(NOM)

'I thirst for your blood.'

The disintentive pali form is often used for the sense of just to be thirsty. This goes contrary to the pattern with 'tocu', where the base form is a term, not a modifier, and in the base form, the base valence is intransitive, not semitransitive. However, the actual usage is quite similar.

This idiom expresses a desire for revenge.

Noun:

As a noun, 'sawyn' refers to the sensation of thirst in general, to the condition of not having adequate water, or to the same kind of metaphorical desire that the verb form deals with.
