Seo é m'fhadhb:
for example 'to come'
I have heard 'a theacht'-'to come'
and I have also heard of 'le teacht' as well, mar shampla 'fós le teacht' - 'still to come'.
Canathaobh nach úsáidtear 'a' sa chás seo (fós a theacht)?
Cad é an dhifríocht eatarthu ar chor ar bith?

Ansin ciallann "le teacht" rud inteacht mar "ready to come" (no "in order to come" in abairti eile).

Ciallann "a theacht" "to come", ni ach an infinitive féin.

Ba mhór an t-ualach dem dhroim é san, go maire tú go deo a Lughaidh.

Ina cheann san, níor mhiste a lua gur féidir frása go bhfuil a + ainm bhriathartha ann a dh'úsáid mar a bheadh cuspóir briathair nó faisnéis na copaile ann. Féach, a leithéid seo:

Ní maith liom (é) a theacht anso chomh luath san ar maidin = I don't like him/his coming here so early in the morning

Ag labhairt ar na leanaí a dhul abhaile luath ón scoil a bhíomair = We were talking about the children going home early from school

Níl as bhéal an bhig is an mhóir fé láthair ach an Taoiseach a (dh')éirí as oifig = Everyone at the moment is talking about the Taoiseach resigning

Polaiteoirí a rá na fírinne, a deireann tú?! Nea-meabhair siar ó thuaidh! = Politician telling the truth, you say? Nonsense of the highest order!

Níor cheart "ag" a chuir in "a" in aon cheann dos na habairtí sin thuas.

Is fíor dhuit, a Lughaidh.

Tá Síle le dul abhaile go Meirice amáireach = Síle is due/suppposed to go home to America tomorrow.

Tá an-chuid oibre le déanamh fós againn = We still have a great deal of work to do
