Grammar both

Hi

There is a sentence for English learners for the term (frond).

Ferns and palms have fronds.

Now I need to add one more word "perennial plant" to this sentence.

Am I correct if I write
Ferns and palms, both perennial plants, have fronds.
????

That works, but I would add this:

Ferns and palms, which are both perennial plants, have fronds.

 

Just curious, who is the target audience for your classes? I noticed you were asking about a sentence with 'tarry' which, while is not an obscure word, is not spoken that often (at least in my circles).

But I've never heard anyone say 'frond'. But I'm not the most cultured person, so that may not mean much.

 

That is grammatically correct (although it adds two words, not one). However, I think the amended version suggested by Opalized is an improvement.

 

Hi Opalized, Bruce Johnson, SapereAude

Thank you !! I will change my sentence as you advised me.

Actually, the needs to add "perennial plant" is coming from this,,,

Target audience is from 13 years to 22 or 23-ish.
This is for TOEFL test vocabulary training.
This vocabulary-build book is for Japanese students.

and the original word "frond" is coming from this

I am going to start my own English-test prep school for junior and high school and college students with my wife from Feb, hopefully.
That is why I am just now preparing my own text book.
The prep school location is near Komagome station , Tokyo, Japan. 7-8 minutes walk from the station.


Again, thank you very much.
