Speed, the auto-contradicting senile sociopath, blabbered, again:


Today, preoccupied, I said to a visiting child who I was about to take
home, "Have you got all your your trankliments?" Meaning toys, shoes,
phones, etc.

Is this word in use in other areas, or is it just Yorkshire?

Not even there

Actually, the word does exist in variant spellings, you obnoxious senile
pest!
