Thanks for your answer, I am glad

Both a boy and a finger could be described with the word little, and also the word small. "A little boy was standing in the road." "A small boy walked over." "There was a picture of a small finger." "She saw a picture of a little finger." But, in the US, when someone talks about their little finger, they mean the specific finger that is farthest away from the thumb. "I got a splinter in my little finger." "She broke her little finger." You could say "a little" if someone asked you "How much cake would you like?" or "How much coffee would you like?". You could also answer "A small piece." or "A little piece" or "A small cup". But you could not just say "a small".

Both words are adjectives related to size. One difference is that "little" can relate to quantity for non-countable nouns. I believe "little" is used more often in American English, and "small" more often in British English.

I think it is....... " a small boy. A little finger".
