remiss

What does "remiss" mean?
To be "remiss" means to be neglectful or careless in one's duties or responsibilities. Imagine a security guard who leaves the gate unlocked or a student who forgets to turn in a major assignment; they have failed to show the level of care or attention that was expected of them. This word is almost exclusively used in formal or professional contexts, often when someone is being held accountable for a mistake. It is frequently paired with "in" (e.g., "remiss in my duties") and carries a weight of professional disappointment rather than just simple forgetfulness.
