4. BRAWDDEG SYML SIMPLE SENTENCE Consist of a single main clause
Every sentence must contain a subject and a verb
Examples:
Ffion ran home.
I like swimming.
Mae’n cynnwys un prif gymal
Rhaid i bob brawddeg gynnwys goddrych a berf
Enghreifftiau:
Rhedodd Ffion adref.
Rwyf i yn hoffi nofio.

5. BRAWDDEG GYFANSAWDD COMPOUND SENTENCE
Consists of two or more main clauses joined using a coordinating conjunction, e.g. and, but, so, or, for and yet.
Each clause still makes sense on its own
Example:
I like swimming but my favourite sport is cycling.
Mae’n cynnwys dau neu ragor o brif gymalau sy’n cael eu huno drwy ddefnyddio cysylltair cydradd, e.e. a, ond, felly, neu, oherwydd, er hyn.
Mae pob cymal yn dal i wneud synnwyr ar ei ben ei hun.
Enghraifft:
Rwyf yn hoffi nofio ond fy hoff weithgaredd yw beicio.

6. BRAWDDEG GYMHLETH COMPLEX SENTENCE
Consists of one main clause and one or more subordinate clauses joined by a subordinating conjunction, e.g. because, if, although, so and since.
A subordinate clause relies on the main clause to make sense
Example:
Osian needs to attend his swimming lessons if he wants to do well at the gala.
Mae’n cynnwys un prif gymal ac un neu ragor o is-gymalau sy’n cael eu huno gan gysylltair isradd, e.e. oherwydd, os, er, felly, ers.
Er mwyn gwneud synnwyr mae’r is-gymal yn ddibynnol ar y prif gymal
Enghraifft:
Rhaid i Osian fynd i’w wersi nofio os yw am wneud yn dda yn y gala.
