/ədˈvaɪs/
[noun] An opinion or suggestion that you give to someone to help them decide what to do or how to act in a situation. For example, a doctor might give you advice about how to stay healthy.
The word 'advice' literally grew from a Latin phrase meaning 'it seems to me' — making every piece of advice originally a humble personal opinion.
The story of 'advice' begins in Latin with the phrase 'mihi visum est', meaning 'it seems to me' or 'it is my view'. The key ingredient here is the Latin verb 'videre', meaning 'to see'. From this root came the noun 'visum', referring to something seen or perceived, and eventually a sense of personal judgment or opinion. This idea of seeing and forming a view would travel a long road before arriving as the word we use today.
In Vulgar Latin — the everyday spoken form of Latin used across the Roman Empire — the phrase evolved into 'ad visum', meaning roughly 'according to what seems right' or 'according to my view'. This 'ad visum' was the seed of the Old French word 'avis', which carried the sense of an opinion, a view, or a considered judgment. Old French was the language spoken in France and by the Norman ruling class in England after 1066, and it became a major pipeline through which Latin-rooted words flowed into English.
From Old French 'avis', the word passed into early Middle English as 'avis' or 'avys', still meaning an opinion or a considered view. Over time, the preposition 'a' at the beginning was reanalysed — that is, English speakers heard it as 'a' plus 'vis', so they reattached a new form of the Latin prefix 'ad' (meaning 'to' or 'toward'), producing 'advis' and eventually 'advice'. By the 13th and 14th centuries, the word was firmly established in English writing, appearing in texts to mean a formal opinion or recommendation.
One of the most fascinating quirks in the word's history involves spelling and sound. In Middle English, the word was often spelled 'advise' — the same spelling used for the verb form today. Over time, English developed a habit of distinguishing nouns from their related verbs by changing the final letter: the noun became 'advice' (with a 'c', pronounced /s/) and the verb became 'advise' (with an 's', pronounced /z/). This split mirrors the same pattern seen in 'device' and 'devise', or 'practice' and 'practise' in British English — a small but elegant system of spelling that marks the difference between a thing and an action.
The meaning of 'advice' has remained remarkably stable across the centuries. While many words drift far from their origins, 'advice' has stayed close to its Latin roots: it is still, at heart, something that 'seems right' to the person offering it. Interestingly, the same Latin root 'videre' (to see) gave English many other familiar words through different paths — Latin 'videre' → Old French 'veoir' → English 'view'; Latin 'videre' → Latin 'providere' → Old French 'pourveoir' → English 'provide'; and Latin 'visio' → Old French 'vision' → English 'vision'. Seeing, in the ancient world, was deeply connected to knowing and judging — and 'advice', at its core, is still someone else's way of seeing your situation for you.
