The Spanish word 'ignorante' (meaning 'ignorant') comes from the Latin word 'ignorans' meaning 'not knowing.' This Latin word derives from the verb 'ignorare' ('to not know'), which was formed by combining two elements: the prefix 'in-' meaning 'not' and the verb 'gnoscere' meaning 'to know.' So literally, 'ignorante' means 'not knowing' or 'lacking knowledge.'

Some related Spanish words include 'ignorar' (to ignore), 'ignoro' (I ignore/I don't know), and 'ignorancia' (ignorance). All these words share the same Latin root and maintain the core meaning of 'lack of knowledge' or 'choosing not to know.'

The English words 'ignore,' 'ignorant,' and 'ignorance' are direct cognates of the Spanish 'ignorante,' all coming from the same Latin root 'ignorare.' Additionally, the English words 'know,' 'knowledge,' and 'cognition' are related to the Latin 'gnoscere' (to know) that forms part of this word family, though these come from the positive rather than negative form of the root.
