By using a “mood” as the noun in the above construction using dhe to you have one way of indicating how you feel, e.g.:
Ma odhom dhebm a ... I need … (literally There is need to me of …)
Ma whans dhebm a ... I want … (literally There is want to me of …)
Ma edrek dhebm. I’m sorry. (literally There is sorrow to me of …)
Ma odhom dhebm a garr nowyth. I need a new car.
Ma whans dhebm a vona. I want money.
As with any other use of Ma There is you form questions by using Eus? Is there? and negative statements by using Nag eus There is not, e.g.:
Eus odhom dhebm a vona moy? Do I need more money?
Nag eus odhom dhebm a garr nowyth. I don’t need a new car.
In conversation with other people you can talk about their needs and wants by using dhis to you (familiar) or dhewgh to you (formal or plural), e.g.:
Eus odhom dhis a vona moy? Do you need more money?
Nag eus odhom dhewgh a garr nowyth. You don’t need a new car.
 This is not the only way of saying “Sorry”.
