Aled ThompsonBlue tit or 'Titw Tomos Las' in Welsh

@ThompsonArt I'm trying to parse the Tomos part. Titw = tit, Las = blue, so what's Tomos?
Cute bird pic :)
@GwenfarsGarden Thank you! That's some good translating! Tomos is the Welsh version of Thomas or Tom and a colloquial name for the blue tit is Tom Titmouse which is where I assume the Tomos came from :)
@ThompsonArt I'm still a very beginner with Welsh, so I'm glad I got some right!
I didn't know that about a Blue Tit being called Tom or Thomas. I never came across that when I lived in England, so is it more a Welsh thing?
@GwenfarsGarden Sounds like you're making good progress!
I believe the Welsh name is just a modern translation of the old English name, with Tom just being a popular nickname from the past (like Jack). The Tomtit name is used for several bird species so I assume the blue tit became more popular to distinguish them, but the old name still lives on through Welsh.
