in fright & with fright
Solution 1:
Both are basically the same. You could argue that in some cases one may seem more natural but that depends on style and tone.
Based purely on instinct (and I can't find a good source):
- "with fright" means that being frightened is the cause of an action
- "in fright" describes an activity done in a state of being frightened
For example:
- "He ran away with fright": he was so frightened that he ran away
- "He ran away in fright": he ran away and he was frightened when doing it
But as noted, this is missing a citation to an authoritative source.
