Hi, Is "paltry" example here right for my text? I understad it as something "very poor" ?
low in quality She made some paltry excuse and left.
"The PAC had raised a fair amount of money in 2005,
but its email list of donors was paltry and so was the cash in Obama’s own campaign
account"
You're right with your understanding of it. If you think about it, it's quite logical. A paltry amount of money is a very small amount of money. If you only have a small amount of money, you're poor. I don't mean that the two meanings necessarily come from the same idea, but it's useful to remember the similarity.
"Poor" is also a synonym for "bad" or at least "not good".
"She made a poor excuse and left."
