"We are heating the vegetables."
Translation:Tá muid ag téamh na nglasraí.
I understand why the genitive plural is used here, with the words forming a complete structure by themselves, what I don't get is the example in the grammar rules where "I am looking for work in London = Táim ag lorg oibre i Londain" is an example for this, yet "I am looking for work in the Government = Táim ag lorg obair sa Rialtas" is an example where the second noun is not in the genitive case because the clause is incomplete without the following prepositional phrase. I realise this is probably not the best place to ask my question but I haven't encountered an example for that yet. Can someone please explain?
