An taigh-beag

Did you get caught out by the last phrase? 

You have learnt the Gaelic for a small house is  taigh beag  and the Gaelic for toilet is  taigh-beag  and we all know this is adorable. When talking about the toilet in the dative case, it’s best practice to lenite the beag. 

Chan eil an t-amar anns an taigh-bheag
The bath isn't in the toilet
