untalented

A frustrated and untalented artist,  Bary crams way too many words in a single sentence for a single line.

She is too vapid and immature (and untalented) to pull off something really seductive.

If it is untalented and unpractical it becomes one of those poor creatures who never get anywhere.

The exceptionally talented man knows anyhow where he belongs, and the exceptionally untalented one will be excluded anyhow.
