Description:

The term 'coza' refers to any solidified, spreadable, water-repelling substance and basically means the same thing as the English word 'wax'. It is also used as the word for 'candle'. The word comes from Old Common.

Old Common had no word for 'candle', but a word was quickly needed in the real world, as even in the early 21st century candles were sometimes used as emergency light sources (but more often as decorative items), and of course today they are one of the major sources of light for much of the world, either intermittently during frequentl power outages, or permanently in areas that are still not electrified.

Noun:

As a noun, 'coza' refers to the substance of wax (as in English, a very broad term that can include natural and artifial waxy substances), or a candle.

Verb:

As a verb, 'coza' is a skurun verb meaning to apply wax to something, with an ergative wax-applier and an absolutive thing waxed.

Modifier:

The modifier form 'cozas' just means having a waxy consistency, or being covered in wax.
