Start with a real moment.
You are choosing between two hotels. One is cheaper; the other is closer to the station. Comparing one feature at a time helps you explain a decision clearly. A superlative changes the frame: “the cheapest hotel in this area” compares one hotel with the whole relevant group.
See how the sentence works.
Subject + be + comparative + than + comparison
Read the sentence as one idea, then notice the job each part does.
Understand the choices.
Many short adjectives use -er and -est: cheaper, cheapest. Longer adjectives often use more and most: more comfortable, most comfortable. Some forms are irregular: good, better, best. Check an unfamiliar adjective rather than applying the length rule mechanically.
Use than to name the other side of a comparison: “This room is larger than ours.” Use the with an ordinary superlative before a noun: “the largest room.” Make the comparison group clear, such as in the building or of the three.
As + adjective + as compares equality: “The bus is as convenient as the train.” Not as … as expresses a lower degree. Use much or a little to modify a comparative: “much faster.” Do not combine more with an adjective already marked with comparative -er.
Useful sentences, in context.
This flight is cheaper than the morning one.
Than introduces the other flight.

On this floor defines the group.
Walking is not as fast as taking the metro.
Use the base adjective fast between as and as.
A small change makes a difference.
AvoidThis bag is more cheaper.
UseThis bag is cheaper.
Cheaper already contains the comparative marker; do not add more.
