ceartharnach

heard only in the very common proverb 'is fada an saol ceatharnaigh bliain' (MCd); dá mbeitheá ag caint ar rud a dhéanamh, déarfaí leat é (MC); 'up today and down tomorrow', therefore do not say what you'll do in the future, you may not be able to do it, you may not be alive Cf. SFC, 2386
