"They are thin and not particularly tall."

[cvolgenau]

Is it acceptable to use sono again before particularmente in this situation.? e.g. Sono Magri e non sono particularmente alti

[f.formica]

Yes, it isn't bad Italian at least.

[Blomeley]

In that case I shall report it as I just got knocked out for doing exactly that :)

[Elephant]

In the case of "Sono magre e non particolmete alti.", should "alti" not be "alte" to agree with "magre"?

[f.formica]

Yes, you should report it.
