English: dual-language immersion

Status B

Subject: Education

Part of speech: Noun, Feminine, Singular

Definition: Addysg drochi lle mae’r dysgwr yn cael ei addysgu mewn dwy iaith gyda’r bwriad o sicrhau ei fod yn dysgu am y pynciau academaidd (yn bennaf yn ei famiaith, neu am yn ail rhwng y naill iaith a’r llall) tra hefyd yn dysgu’r ail iaith.

Notes: Gwelir y ffurf 'addysg drochi ddeuol' hefyd. Argymhellir defnyddio 'addysg drochi dwy-iaith' lle bo modd. Mewn rhai cyd-destunau, mae'n bosibl y byddai 'trochi dwy-iaith' (heb yr elfen enwol 'addysg') yn addas.
