However, in this case, the word 'osservatrice' itself already has the feminine ending '-e'. But 'un' is a masculine indefinite article, so when used with a feminine noun, an apostrophe is added to 'un' to make it 'un'' which is the shortened version of 'una'. This is to indicate that you are referring to a feminine noun."}]
