I think you’re asking for Jain terms that start with the letter D (from later Jain scriptures). Here are some common D-terms with simple, authentic meanings, noting any traditional differences where relevant:

• Dharma: The path of virtue and righteous conduct; in Jainism it also denotes the cosmic law and religion that leads to liberation.
• Darshan: Right faith or correct perception of the true nature of souls and substances.
• Daya: Compassion or kindness toward all living beings.
• Dana: Charity or giving with a sincere, non-attached attitude.
• Diksha: The formal initiation into monkhood or renunciation (important in both Digambara and Śvetāmbara traditions, with tradition-specific practices).
• Dhyāna (meditation): Contemplative practice; in Jainism this is connected to concentration and moral discipline, though common Jain practices emphasize samayik and tapas rather than generic meditation in some sects.
• Dravya: A fundamental substance; in Jain metaphysics the seven dravyas include jiva (soul), pudgala (matter), etc., forming the world.
• Deshna/Deshana: A sermon or instruction given by a monk or acharya.
• Dosh (fault) or Dosha: A fault or defect in conduct or thought to be overcome on the path to purity; discussed in ethical teachings.

Notes:

• Digambar and Śvetāmbara traditions generally agree on core meanings of these terms, but there can be nuanced interpretations or emphases in scriptures, practices, or liturgical usage. If you’d like, I can outline where meanings differ between the two traditions for any specific term.
• If you meant a different scope (e.g., terms specifically from a certain scripture or a particular time period within Jain literature), tell me and I’ll tailor the list.
