'Wenig' has a special feature: when it stands before a noun without an article, it is often not declined. However, when it stands alone as a pronoun or after an article, it must be declined.
Ich habe leider nur wenig Zeit.
Unfortunately, I only have a little time.
The comparative forms of 'wenig' are 'weniger' (less/fewer) and 'am wenigsten' (the least/the fewest). These are used to compare quantities with one another.

The expression 'ein wenig' is a fixed unit and means 'a bit.' It is not declined and can be used to soften a statement or describe a small amount.

When 'wenig' refers to people or things that are already known, it functions like a pronoun. In this case, it often stands at the beginning of the sentence and is declined.

something / somewhat
'etwas' and 'wenig' can both express a small amount. 'etwas' often sounds neutral and simply means 'a little' or 'some'. 'wenig' puts more emphasis on the fact that the amount is small, sometimes even too small. That is why 'Ich habe etwas Zeit' sounds rather positive: there is a little time available. 'Ich habe wenig Zeit' sounds more limited: there is not much time available. They are confused because both can be used with amounts, but the effect is often different.
