Which one do I choose in my multilingual website - subdomain or subdirectory?

Do subdomains have their own DA or is it the same as the main domain?

subdomains are treated as different sites by google, so yes, they have their own DA.

both will work, but I've seen more sites using directories than subdomains

They both work for SEO.

In tools the DA will be that of the root.

Both have their pros and cons. Subdomains provide separate entities with their own URLs, but they don't inherit the domain authority of the main domain. On the other hand, subdirectories are part of the main domain and benefit from its DA. Ultimately, it depends on your specific goals and requirements.
