Inventing words?

[XerXesXu]

Yes. If a new word is needed I coin one. A couple of days ago I coined 'polyamour', there was no existing single word and I wanted to avoid excessive explanation.

If no one invented words we wouldn't have any.

Another recent coinage occurs to me, 'advergarment'.

"Meantime, I watch the street life pass by, especially the go-go dancers in their skimpy 'Love for Sale' advergarments on their way to work. "
