Mirepoix (cuisine)
Similar flavour bases include the Italian "soffritto", the Spanish "sofrito", "refogado/sufrito" (braised onions, garlic and tomato) from Portuguese-speaking nations, the German "suppengrün" (leeks, carrots and celeriac), the Polish "włoszczyzna" (leeks, carrots, celery root and parsley root), the US Cajun / Creole holy trinity (onions, celery and bell peppers), and possibly the French "duxelles" (mushrooms and often onion or shallot and herbs, reduced to a paste).
Trident
The word "trident" comes from the French word "trident", which in turn comes from the Latin word "tridens" or "tridentis": "tri" meaning "three", and "dentes" meaning "teeth", referring specifically to the three prongs, or "teeth", of the weapon. The Sanskrit name for the trident, ""trishula"", is a compound of "tri" त्रि for "three" + "ṣūla" शूल for "thorn", calling the trident's three prongs "thorns" rather than "teeth".
