Usage Note
Arglos (without suspicion, literally 'without ill') describes someone who harbours no ill intent themselves and does not suspect it in others. It is positive when describing innocence but can imply dangerous naivety when the arglos person is being exploited.
Examples
"Die arglosen Touristen merkten nicht, dass man ihnen die Geldbörse gestohlen hatte."
Natural Translation
The unsuspecting tourists did not notice that their wallet had been stolen.
Literal Translation
The guileless tourists noticed not, that one them the wallet stolen had.
