The term can be neutral or negative depending on context.
Use 'uninformed' or 'unaware' instead of 'ignorant' to sound more neutral.
'Ignorant' can be offensive if used to describe people rather than situations.
From Middle English 'ignorant', from Old French 'ignorant', from Latin 'ignorans', present participle of 'ignorare' (to not know).
While 'ignorant' can describe a lack of knowledge, it is often used to imply a negative judgment about someone's lack of awareness.
