====Conditional complementation====
A conditional clause gives the condition under which something will happen. In Irish there are two kinds of conditional clauses, depending on the plausibility of the condition. The particle {{Lang|ga|má}} introduces a conditional clause that is plausible, also called a ''[[conditional sentence#Factual/predictive conditions|realis condition]]''. {{Lang|ga|Má}} causes lenition and takes the independent form of irregular verbs. Its negated form is {{Lang|ga|mura}} and causes eclipsis. Preceding the preterite it is {{Lang|ga|murar}} and causes lenition.

If the condition of the clause is hypothetical, also called an ''[[conditional sentence#Hypothetical (counterfactual) conditions|irrealis condition]]'' or ''[[counterfactual conditional]]'', the word {{Lang|ga|dá}} is used, which causes eclipsis and takes the dependent form of irregular verbs. The negated equivalent is either {{Lang|ga|mura}} or {{Lang|ga|murach go}}, meaning roughly "if it were not the case that...". The verb in both clauses is in the conditional.
*(48a) {{Lang|ga|'''Má''' chreideann sé an scéal sin, tá sé saonta go maith.}} "If he believes that story, he is pretty gullible." (realis)
*(48b) {{Lang|ga|'''Murar''' chaill sé é, ghoid sé é.}} "If he didn't lose it, then he stole it." (realis)
*(48c) {{Lang|ga|'''Dá''' bhfágfainn agat é ní dhéanfá é.}} "If I left it to you, you wouldn't do it." (irrealis)

Other examples of conditionals are: 
*(49a) {{Lang|ga|Éireoidh leis an bhfiontar '''i gcleithiúnas go''' mbeidh cách páirteach ann.}} "The venture will succeed '''provided that''' all take part in it."
*(49b) {{Lang|ga|Tig leat é a bhriseadh '''ar chuntar go''' n-íocfaidh tú as.}} "You may break it '''provided that''' you pay for it."
