The word 'blister' is used when a person's skin becomes raised and filled with fluid due to friction, heat, or some kind of pressure. For example, if you wear tight shoes for a long time, you may get blisters on your feet. It's important to keep the blister clean and avoid popping it, as this can cause infection. The word 'blister' can also be used to describe a container that is used to hold tablets or capsules, such as a blister pack.
