Root Explanation

Aldehyde is derived from the term 'alcohol dehydrogenatum', which means 'alcohol without hydrogen'. The prefix 'al-' comes from the Arabic 'al-', meaning 'the', and 'dehydrogenatum' is from Latin roots 'de-' (meaning away from) and 'hydrogen' (meaning water-forming). The word describes a compound formed from alcohol by the removal of hydrogen.

Memory Tip

Think of 'al-' as 'the' and 'dehydrogenatum' as removing hydrogen from alcohol — that's how aldehyde is formed from alcohol.
