Fòram na Gàidhlig

In the part of the saying 'Blood of my veins, bone of my bone...' (Is tu fuil o mo chuislean, is tu cnaimh de mo chnaimh) Why in 'Is tu fuil o mo chuislean.' would you use the noun 'cuislean' and not 'cuisle'?

I would really appreciate if someone can help me out with this. I've been scratching my head over it all day.

It's the plural

Haha oh, yes makes sense
Thank you!

Sorry I'm a beginner

No worries, it can be a bit confusing, since -an can be both a diminutive (pronounced /an/) and a plural ending (pronounced /ən/).
