Welsh and Irish are both classified as Celtic languages but are too different for mutual comprehension. Irish and Scottish Gaelic would be more mutually intelligible.
Irish is spoken in Ireland, Scottish is spoken in Scotland, English is spoken in England, and Welsh is spoken in Wales. Each language has its own unique linguistic characteristics and cultural significance within its respective country.
How did cavemen understand each other
The Irish Gaelic word is capall. The Scottish Gaelic is each. The Welsh word is ceffyl or march. The Cornish word for Horse is Margh. There is not a single Celtic language but six. The others are Manx Gaelic and Breton.
No, but many understand each others alarm calls.
There are several different Celtic languages, not just one- Welsh, Scots Gaelic, Irish Gaelic, Cornish, Breton and Basque (there is also Manx Gaelic as well, although this is now considered to be a 'dead' language). The word for 'time' differs in each case; I am Welsh-speaking, and 'time' in Welsh is 'amser' (pronounced 'umsarr', with the 'r's rolled). For 'time' in the other Celtic tongues, try searching Celtic Languages on Google.
Italian and Irish people generally get on very well together.
