Ordinal numbers
Àireamhan òrdail
We use àireamhan òrdail (ordinal numbers) to say what the order or position of someone, or something, is in a sequence: a' chiad àite (the first place), an còigeamh latha (the fifth day). In Gaelic these numbers use an – amh ending, in a similar way to the '–th' ending used in English. The abbreviation used when writing is mh (th), although 1d is used for '1st', and 2na for '2nd'. When a noun is used with the teen numbers it comes before deug : dàrna latha deug .
