Is it possible to output a post in a form ?

Hello,
I just had a begginer doubt. I’m starting with computers via wordpress, and I’m learning little by little, so probably it makes no sense what I’m after.

Here it goes:

Can I output a post, as a default text, in a form (let’s say, a ‘textarea’) ?

I’ve tried to put a <?php the_content(); ?> in a textarea but nothing happens.

I’d like to know any known workaround, if possible.

Thanks !
