What are the hisorical reasons for the use of the Irish language derived terms TD (for MP), Taoiseach (for PM) and Ceann Comhairle (for Speaker of the house), but not the term for President (Uachtarán)?

by myothercarisawhale

Was it because of the later creation of the office? Was it due to the office of president's foreign focus?

Edit:I mean in English in Ireland, probably should've specified that in the title just to be clear...

The best reason I can offer is that it is the only one of those offices that is primarily referred to in English in the constitution. I have never seen a reason for it. I suspect it is that there was no English equivalent and therefore no need to distinguish the office.
