Sense: noun/1
A psychologist holds a university degree (often a PhD or master's) in psychology and studies the mind, emotions, and behaviour. A psychiatrist is a medical doctor (MD) who specialises in mental illness and can prescribe medication — this is the key legal difference. A therapist is a broader label covering anyone trained to provide talk therapy, including psychologists, social workers, and marriage counsellors. A counsellor typically has fewer years of training than a psychologist and focuses on specific problems such as grief, addiction, or career choices. For example, someone with long-term depression might see both a psychiatrist for medication and a psychologist for weekly talk therapy, while a person coping with a recent divorce might only need a counsellor.

Etymology
The word 'psychologist' was formed in English in the 1700s from 'psychology' (the study of the mind) plus the suffix '-ist' (someone who practises or studies something). 'Psychology' itself comes from two Greek roots: 'psyche' (ψυχή), meaning 'mind, breath, or soul', and 'logia' (λογία), meaning 'study of' or 'discourse'. So a psychologist is literally someone who studies the mind.
