Editing 'spiritus'

Hello, CodeCat! I tried to edit the page for spiritus by adding that the Greek word for 'match' σπίρτο is also a descendant. I didn't know the language code during the process but have since found the Wiktionary language-code page. May I try to edit the page again?

But is it really a descendant? I don't immediately see a connection between "match" and "spirit".
