Daearyddiaeth - Geography
From the Wikipedia - Conjunctions "In grammar, a conjunction (abbreviated CONJ or CNJ) is a part of speech that connects words, phrases, or clauses...."
In the above sample sentence we have used the conjunction 'ond' (but) to join the two short sentences:-
Dwi'n hoffi daearyddiaeth.
Dwi ddim yn deall mapiau.
You may, by this point, be tired of forming simple Welsh sentences with only a single clause. Why not take a look at some of the other sample sentences on the noun pages of the 'Geiriadur' and see if you can form more complex sentences by using conjunctions? e.g.
Dwi'n hoffi pysgod a sglodion ond dwi ddim yn hoffi selsig.
(I like fish and chips but I don't like sausages.)
Dw i'n mynd i Gaerffili yfory ond dwi ddim yn mynd i Gaerdydd
(I'm going to Caerphilly tomorrow but I'm not going to Cardiff)
