Which term describes assistance offered in time of difficulty?

Succor is the term that refers to assistance or support provided during times of difficulty or distress. It embodies the idea of offering help to those in need, especially when facing challenges or crises. The word derives from Latin and suggests not just any kind of help but specifically aid that alleviates suffering or hardship.

In contrast, the other terms do not convey this meaning. Turpitude refers to moral depravity or wickedness, which is unrelated to assistance. Vaunt means to boast or brag about something, often exaggerating one's achievements rather than providing help. Tyro describes a beginner or novice in a particular field, which also does not connect to the concept of offering aid. Thus, succor stands out as the appropriate term for assistance in times of difficulty.
