/ədˈvaɪz/
[verb] To give someone your opinion or recommendation about what they should do in a particular situation. It can also mean to formally inform someone of something important.
At its heart, 'advise' means 'to look toward' — as if wisdom were simply a matter of pointing your eyes in the right direction.
The story of 'advise' begins in Latin, with the deceptively simple verb 'videre', meaning 'to see'. From this root came the Latin phrase 'ad visum', meaning roughly 'according to what is seen' or 'toward a view'. This evolved into the Vulgar Latin verb 'advisare', which carried the sense of 'to look at' or 'to consider carefully'. The idea was that giving good guidance required first taking a clear, steady look at a situation — seeing it fully before speaking.
From Latin, the word passed into Old French as 'aviser', meaning 'to notice, to consider, or to counsel'. Old French was a language deeply influenced by the Latin of the Roman Empire, and it carried many of these 'seeing' metaphors into its vocabulary. In Old French, 'aviser' had a practical, everyday quality — it was the word you used when someone stopped, thought carefully, and then offered their view. The connection between 'seeing' and 'knowing' was natural and intuitive to speakers of the time.
English borrowed 'aviser' from Old French in the 14th century, initially spelling it 'avisen' or 'avise'. Middle English absorbed enormous numbers of French words during this period, largely as a result of the Norman Conquest of 1066, which had placed French-speaking rulers over an English-speaking population. By the time 'advise' settled into English, it had gathered its modern meaning: to offer guidance or recommendations to another person. The spelling gradually shifted toward 'advise', partly influenced by the Latin 'ad-' prefix, meaning 'toward'.
One fascinating aspect of 'advise' is how it kept its two distinct senses across the centuries. On one hand, it means to recommend or counsel — 'I advise you to rest'. On the other hand, it means simply to inform — 'Please advise us of your arrival'. Both meanings trace back to that original idea of 'directing one's sight', whether toward a course of action or toward a piece of information. The formal, informational sense is especially common in legal and business writing today.
The word's close relative, 'advice', came into English by a slightly different route. Old French 'avis' (meaning 'opinion' or 'view') became Anglo-Norman 'avis', which English turned into 'advice' in the 14th century. Interestingly, 'advice' (the noun) and 'advise' (the verb) look almost identical but are spelled differently — a distinction that still trips up writers today. This difference in spelling reflects the French influence: in French, the noun and verb forms were clearly separate words, and English preserved that separation even as pronunciations grew closer. Together, 'advise' and its family of words remind us that some of our most practical, everyday language is built on something as poetic as the simple act of looking.
