Sense: adjective/2

All four words describe a careful, considerate way of handling people or situations, but they differ in emphasis. 'Tactful' is the most common everyday word — it means knowing what to say (or not say) so as not to hurt someone's feelings. 'Diplomatic' is slightly more formal and suggests the skill of managing a difficult situation between two or more parties, like a negotiator. 'Politic' (formal) focuses on what is wise or advantageous given the circumstances, not just kindness. 'Discreet' is about keeping confidences and not drawing attention, rather than being gentle with words. For example: 'It was tactful of her to praise both teams.' 'He gave a diplomatic answer that avoided blaming anyone.' 'It was politic not to mention the budget cuts at the party.' 'She was discreet about the merger and told no one.'

Etymology

GreekLatinFrenchEnglish

The word 'diplomatic' entered English in the early 1700s from French 'diplomatique', which came from Latin 'diplomaticus' and Greek 'diplōma' (διπλωμα), meaning 'folded paper' or 'official document'. This is because early diplomats carried folded, sealed documents as credentials. The sense of 'tactful' developed in the 1800s, drawing on the idea that good diplomats must be skilled at handling sensitive situations with care.
