I would like to get faith in Japanese for a tattoo. This is what I’ve seen. “信” and “信頼“ What is the difference between the two?
I believe that "信" has the meaning of trust or believing in something, for example:
Do you believe in fairies?
Whereas "信頼" is the word I would use for a more "serious" kind of trust, for example:
I have complete trust in my doctor.
If you want the term "faith" in a religious sense for your tattoo I would look into "信仰" instead. Another example:
My mother believes in Christianity.
I took all of these examples from Jisho.org, a place I would recommend you consult before getting your tattoo!
