Gefährlichkeit vs Gefahr
danger
'die Gefahr' and 'die Gefährlichkeit' look similar, but they do not mean the same thing. 'Gefahr' refers to a concrete threatening situation or a risk: something can happen and cause harm. 'Gefährlichkeit' refers to the quality or degree of how dangerous someone or something is. Learners may confuse the words because both come from the adjective 'gefährlich'. In practical terms: for a situation, you usually say 'Gefahr'; when judging how dangerous something is, 'Gefährlichkeit' fits.
