What does counsellor mean?
A counsellor is a person whose role is to advise, guide, or support others, typically through training in a specialised field. In everyday usage it most often denotes a mental-health or wellbeing professional who helps people work through personal difficulties, from anxiety to relationship problems. It also applies to advisers in institutional settings — a school counsellor guiding students, a legal counsellor offering expertise — and to supervisors at camps and youth programmes. The word carries warm connotations of empathy, confidentiality, and professional support. Spelling varies regionally: British English writes 'counsellor' with a double 'l', whereas American English prefers 'counselor'. Derived from Latin roots shared with 'council' and 'counsel', the word has long been associated with trusted advice-giving. Its versatility across therapy, education, law, and recreation makes it a valuable term to know, though its meaning always centres on someone who listens, advises, and supports.

"As a summer camp counsellor, he was responsible for a dozen energetic eight-year-olds."
Regular plural. British spelling retains the double 'l' before adding '-s'; American English pluralizes 'counselor' as 'counselors'.
"The retreat had more than twenty counsellors on staff."
In American law, 'Counselor' isn't just for therapists — it's how lawyers are formally addressed, so attorneys get called the same thing as school psychologists.

Etymology of counsellor
Counsellor traces back through Old French 'conseiller' ('to advise') to the Latin 'consilium', meaning deliberation, plan, or counsel. This same root gives us 'council' and 'counsel', which is why the words look and sound alike today. The agent form 'counsellor' entered English via Anglo-Norman French, first appearing in the medieval period as a title for trusted royal and legal advisers. Its modern sense of a psychological or therapeutic helper developed much later, alongside the growth of counselling as a profession in the twentieth century.
