I see in some situation the sentence " we have arrived safe" or " we have arrived safely"
I personally still wonder if which sentence is correct.once I got a quiz on a certain webpage.There I got a question where I had been asked to put "safe / safely" on a sentence such as the above-mentioned.There I used " safely" and unfortunately I got it wrong. That means the answer was "safe" But in Cambridge dictionary It is clearly referred to " we all arrived safely". sometime we hear or see " be safe". Here I don't understand whether "safe" is used as an adjective or an adverb. It's ok.what I need is just to make sure if which is correct or suitable to use accurately.
