Traduko - Franca-Latina lingvo - Je fais confiance à tout le monde, ce dont je me...

1) attentus = attentive, intent, businesslike, careful (esp. about money).

-->

"to be afraid of" = timere, metuere, vereri

2) "est" definitely should be put at the end of the sentence.

I think I have a lapse of memory about the position of verbs in Latin, I'll revise it as soon as possible

So, what about "is quem timeo diabolus intra omnem hominem est"?

I would cancell "is" and I am not sure if "quod" wouldn't be better here, even if "diabolus" is a person...

Haha! Yes, it is difficult sometimes to decide which word order to use. And in fact we don't have to always follow word order rules (for example: when we want to emhasise some word).
But we do have to avoid for example this kind of placing verbs together: "..sum est.." (vide: your translation)

What if we use "vereor"? I've just checked in my dictionary that it can be followed by accusativus OR by de + ablativus.
In the latter case it means "to be worried/anxious for". Not very different meaning, and in this way the problem quem/quod disappears.

Yes, I like it very much!
This is one of those I suggested before and it means: to fear, be afraid, to revere, to respect...

Thank you very much!

So you are absolutely sure that : "Omnibus confido, de quo vereor diabolus intra omnem hominem est." is the good translation?
I'm sorry but I have to be sure because a tatoo is for life.

Thank you again!

Maybe "Omnibus confido, id de quo vereor diabolus intra quemque hominem est" is clearer.

Yes, I also find it clearer.
And what do you think, Alex?

I agree with you, girls.
Grazie Serena

I'm glad then.
So, I think this version can be used in your tattoo, mikanof.
