Reference:
- Positive degree: The primary form of an adjective or adverb; denotes a quality without qualification, comparison, or relation to increase or diminution.
- Comparative degree: the form an adjective or adverb takes to compare two things.
- Superlative degree: the form an adjective or adverb takes to compare three or more things.
Positive degree
This house is big.
This house is not as big as that one.
A faint idea.
I had a faint idea about what to do.
Comparative degree
This house is bigger than that one.
As time passed I had a fainter idea about what was going on
Superlative degree
This is the biggest house in this street.
I did not have the faintest idea about what was going on.
So the original question
I did not have the faintest idea about what was going on.
Is in the superlative. The question is asking to change just the adjective "faint" and to take it all the way down to the positive degree which would likely yield:
I did not have a faint idea about what was going on.
Addition on POSITIVE
As far as I can see, the word 'faintest' is used here in a negative
sense i.e. the person's idea was worse than a faintest idea. Any idea
about how to change the degree of the adjective (to comparative and
positive) keeping the meaning of the sentence same?
No it's not :) The word 'faintest' is an adjective that describes the noun 'idea'. The negative, the word 'not' is used with the verb 'to do'.
I did have the faintest idea
I did not have the faintest idea
It's a different meaning of the word "positive". Changing the verb from negative to positive (positive statement) means changing I did not to I did. This is completely independent to changing the adjective from positive (primary form) to comparative to superlative. It's just confusing that the word positive is used in both cases.
When I say that the meaning is same, I mean that the meaning conveyed
by the degree of the adjective must remain the same. Here is an
example: "London is the busiest city in the world" (Superlative)
"London is busier than all other cities in the world" (Comparative)
"No other city in the world is as busy as London" (Positive).
As a rephrasing exercise see:
Positive verb, superlative, comparative and positive degree adjective
- Even after a week of study, I barely had the faintest idea about what was going on.
- After time passed, I had a fainter idea about what was going on.
- After weeks of study, I had a faint idea about what was going on.
Negative verb, superlative, comparative and positive degree adjective
- Everyone else seemed clued in but I did not have the faintest idea about what was going on.
- I did not have any more of a fainter idea about it than the next guy.
- Everyone else understood but I did not a faint idea about what was going on.
So I order to rephrase these types of sentences, the key point is to find a comparison. If you are trying to use "a fainter" idea, which is the hardest, then thing "compared to what"? Compared to the idea that someone else has? Compared to the idea I had yesterday? And keep the adjective comparison separate from the verb.
