What does didact mean?
A didact is a teacher — but rarely a neutral one. The noun denotes an instructor, often one with a pronounced taste for lecturing, correcting, and moral improvement, so it frequently carries a faint edge of criticism: a didact is someone who cannot resist turning conversation into a lesson. The word is uncommon in everyday English, appearing mostly in literary essays, reviews, and formal writing, where its slightly antique flavor suits portraits of schoolmasters, professors, and other inveterate explainers. It belongs to the same family as the far more familiar adjective 'didactic', which describes teaching intended to instruct or edify, sometimes tediously so. Where 'didactic' characterizes a text or tone, 'didact' names the person behind it. Writers who want a compact, elevated alternative to 'pedagogue' or 'schoolmaster' will find it serviceable, provided they accept that many readers may be meeting it for the first time.

Etymology of didact
The word didact derives from Greek 'didaktos', meaning 'taught', from the verb 'didaskein', 'to teach'. English borrowed it in the seventeenth century, alongside the adjective 'didactic' from Greek 'didaktikos'. The same root underlies 'didactics', the theory of teaching, and compounds such as 'autodidact', a person who has taught themselves.
How didact is actually used
Didact is a rare and somewhat literary word; most writers reach for the adjective 'didactic' instead, and readers may encounter the noun chiefly in older or deliberately formal prose. It can carry a mildly pejorative shade, implying someone who teaches pompously or insists on instruction where it was not asked for.
