Perhaps? (¿Quizas?) Sometimes?
A mortal that “frets” is in a state of anxiety (estado de ansiedad), who looks visibly anxious (visiblemente ansioso). Another similar word (verb) in Spanish would be “preocuparse”.
Some examples.
Do not fret (no te preocupes): your operation (su intervención quirúrgica) will go well.
There is no need to fret (no hay necesidad de preocuparse).
Do not fret – I will find a solution (encontraré una solución).
There is another use: a fret (un traste). Guitars have frets, and violins do not have frets.
So, are you sometimes a fretter (a person that has states of anxiety)?
