Which one is right? (there are two ls[or l's] in the word little)

[vaok]

there are two ls(or l's) in the word little.

ls or l's ?

I think the second (l's) is correct.

I presume you could also write there are two "l" in the word little, without specifying the plural.

[vaok]

thank you.

what about other letters?

[druitaly]

I think it is the same but I am not 100 % sure. Sorry.
