Thread:Support/New plural rules for Scots Gaelic (gd)/reply (10)

0 does not trigger any changes not covered by the four forms (it would be 0 + Form 4). But I take it you mean if a sentence like "there are 0 users logged in" would be "there are 0 users logged in" or "there are no users logged in"? The second would be more natural but it would not be a major problem if we had "there are 0 users logged in" in Gaelic.

Yes, 1 and 11 go together because in Gaelic 1 cause a morphophonemic change; as 11 is treated as 1 NOUN 10, the same rule applies, for example: 1 chat - in words aon (1) chat 11 chat - in words aon (1) chat deug (10)

Beyond that, no, there are no other chages (such as the is/are difference in English). In Gaelic the verb only reflects the status of declarative/interrogative/negative but does not change with number (fortunately... there is enough bizarre stuff going on!).
