Status B

Subject: Transport

Part of speech: Noun, Masculine, Singular

Plural: tryciau picyp

Definition: Cerbyd ysgafn gydag ochrau isel yn y cefn, a ddefnyddir yn bennaf ar gyfer cludo nwyddau, ac a all fod â chab sengl neu gab dwbl.

Context: Gallai cerbyd 3 tunnell fod yn fan fasnachol fach, yn dryc ysgafn neu’n dryc picyp a ddefnyddir ar gyfer danfoniadau, gwaith cynnal a chadw neu waith cyfleustodau.

Notes: Mewn rhai cyd-destunau annhechnegol, lle gall y term technegol ‘tryc picyp’ fod yn adlewyrchu ffurf lafar Gymraeg nad yw’n addas i gywair y testun, gellid ystyried defnyddio ‘tryc agored’. Serch hynny sylwer y gall rhai mathau o dryciau picyp, yn enwedig tryciau picyp cab dwbl, fod â chefn caeedig yn hytrach nag agored felly dylid osgoi ‘tryc agored’ os oes angen manwl gywirdeb neu os oes risg o gamddealltwriaeth.
