훨씬 (hwol-ssin) – far (better)/much (better)
훨씬 is only used in comparisons. Therefore, be sure to add in either ~보다 (more/less than) and/or 더 (more) in the sentence when using 훨씬.
훨씬 is not to be confused with other words like 많이 (a lot) 아주/너무/매우 (very much) as those work fine by their own.
But they are similar in the sense that 훨씬, 많이, 아주, 너무, 매우 are all used to describe things at extreme or large extents.
Examples:
