Description:

The term 'wiru' refers to complex arts and crafts. Davidson wrote that the work was coined with 'wero'. While the latter belongs to Old Common's concrete gender, 'wiru' belonged to the 'abstract' gender. They have overlapping meaning and grammar, but 'wiru' emphasizes the complexity, cleverness and design of the action, as opposed to 'wero' which emphasises immediate action with an intention to create a specific effect.

Differences with wero:

Wiru is not used to form causitives. It does, however, have a suffix form -(w)iru. It is used to derive words for complex arts, crafts or disciplines. These words started out as normal compounds with 'wiru', and in early period Common, were completely regular. During the middle period, the 'w' was increasingly omitted in speech following a consonant, perhaps due to the fact the syllable is always unstressed in compounds, and this began to be reflected in writing. When the language was codified in the early modern period, this irregularity was officially recognised.

Noun:

As a noun, 'wiru' is a general word for art or craft in general. The derived form 'wirutuin' is an artist or craftsperson. The derived from 'wiruka' is an article of craft or a work of art, and tends to sound very complimentary. the derived form 'uwíru' has the sense of 'invention'.

Verb:

As a verb, 'wiru' is a skurun verb with an ergative artist or craftsperson and an absolutive thing crafted or created. The derived form 'uwíru' has a similar pattern but with the sense to invent.

Modifier:

The modifier form 'wirus' means clever, creative, intricate or complex and is usually used to describe creative things. It can also mean 'artificial', but the connotation is positive. 'Weros' could be used to get a more neutral or negative connotation.
