Subject: ICT
Part of speech: Noun, Masculine, Singular
Definition: Maes yn y gwyddorau cyfrifiadurol lle datblygir peiriannau a all arddangos neu efelychu agweddau ar ddeallusrwydd dynol.
Notes: Dyma'r acronym a ddefnyddir am artifical intelligence / deallusrwydd artiffisial. Gan bod y ffurf acronymaidd "AI" mor gyffredin a chyfarwydd, argymhellir rhoi blaenoriaeth i drosi enghreifftiau o'r acronym "AI" mewn testunau Saesneg â'r un acronym mewn testunau Cymraeg. Nid oes raid rhoi blaenoriaeth i drosi'r acronym Saesneg â'r term llawn Cymraeg, er y gellid gwneud os oes rheswm da dros hynny.
