The Grand dictionnaire terminologique (GDT) is an online terminological database containing nearly 3 million French, English and Latin technical terms in 200 industrial, scientific and commercial fields.
The GDT has existed in a number of formats over the years, including a dial-up service known as Banque de terminologie du Québec (BTQ), and a CD-ROM version. LGDT is now available only as a freely-accessible web site.
Produced by the Office québécois de la langue française, the GDT is the result of thirty years of work by Quebec-based terminologists. It is the most complete translation resource for Canadian English-language technical terms.
