The Centre for the Greek Language's free portal: Triantafyllidis dictionary and more.
About this tool →Details
A state-backed portal hosting the Triantafyllidis Dictionary of Standard Modern Greek — the reference monolingual dictionary — together with modern Greek grammars, searchable text corpora, dialect lexicons and teaching material for Greek as a foreign language, including distance-learning courses at A1–B1. Everything is free and ad-free. It is a scholarly site in Greek, laid out for researchers rather than learners, so expect to navigate it rather than be guided through it.
