[Question] How does spanish domain name effect seo?

I want to register a Spanish domain name (.com) and build an English language site.
How does it effect seo?
An example
English Spanish
Contact contacto
Contacts contactos

I had a similar doubt years back and I registered 3 domain names (Same niche).
1. German name with .com
2. English name with .de
3. German name with .de

When it came to case 1, I was able to rank the site in UK region but faced a bit of challenge when it came de market as entire content was written in English

When it came to case 2, I was able to generate impressions and did proper on-page, got some links but couldn't make to page 1 ever as content was in English and used a translator plugin it.

Within a span of 3 weeks, with similar keywords and native content, I was able to rank for the targeted terms of case 2.

Hope this might help you!

I have one that is a two word, one spanish one english word and ranked fine due to age, good history and the large backlink profile.

It seems to me that its easier to get one word Spanish .com domains and most one word English .com domains are taken.
