The term 'more expensive' can be described in a variety of ways, such as 'DEAR', 'STEEP', 'pricier', 'costlier', and 'HIGHER'. Each of these words has a different number of letters, but they all refer to the same concept of something being more expensive than something else. In general, when something is more expensive, it means that it costs more money than something else. This could be due to a variety of factors, such as the quality of the item, the rarity of the item, or the demand for the item.
