at a loss
Describes a state in which a person does not know what to do or how to react to a problem. They feel helpless and have no idea for a solution.
Nach der unerwarteten Absage stand er ratlos da und wusste nicht, wie es weitergehen sollte.
After the unexpected cancellation, he stood there at a loss and did not know how things should continue.
The word is made up of 'Rat' (advice, in the sense of good counsel) and the ending '-los' (without). So someone who is 'ratlos' (at a loss) is literally 'without advice'.
Ich bin völlig ratlos, wie ich dieses Problem lösen soll.
I am completely at a loss as to how I should solve this problem.
'Ratlos' (at a loss/perplexed) is often used with verbs that describe a state. Typical combinations are 'ratlos sein' (to be at a loss), 'ratlos wirken' (to seem perplexed), 'ratlos dastehen' (to stand there at a loss), or 'jemanden ratlos zurücklassen' (to leave someone perplexed).
Nach seiner Rede ließ er das Publikum ratlos zurück.
After his speech, he left the audience perplexed.
Often, 'ratlos' (at a loss) is followed by a subordinate clause that explains why the person is at a loss. This clause often begins with a question word such as 'was' (what), 'wie' (how), or 'wo' (where).
Er war ratlos, was er als Nächstes tun sollte.
He was at a loss as to what he should do next.
uncertain / insecure
You are unsicher when you are unsure about different options or do not know exactly which one is right. You are ratlos when you have no idea at all how to solve something. So unsicher is more appropriate when options are available, while ratlos is more appropriate when there seems to be no way out.
