We use adverbs of degree to qualify what we are talking about. I’m really happy, I’m quite happy or I’m not very happy.
Adverbs of degree can be split into two groups:
adverbs that intensify the degree of something
vs.
adverbs that weaken the degree of something.
Adverbs that increase, or intensify, the meaning include words such as: very, totally, completely, and absolutely. For example: I’m totally convinced Sam will quit his job.
Adverbs that decrease or weaken the degree of meaning include words such as: fairly, quite, slightly, and a bit. For example: I’m fairly certain it will rain tomorrow.
1. Weakening the meaning
There are times in English when we want to specifically describe our use of an adjective or adverb. For instance, we may wish to express that we are quite nervous or a bit cold. This is more exact than just saying I’m nervous or I’m cold. The adverbs in this category are all used in the same way. The position of the adverb is before the adjective or adverb.
2. Intensifying the meaning (gradable adjectives)
There are many adverbs that intensify, or make the meaning stronger. For grammatical reasons, we need to separate these adverbs into two groups. Our choice of adverb depends on whether the adjective (which the adverb is intensifying) is gradable or ungradable.
For example, ‘hot’ is a gradable adjective, but ‘boiling’ is ungradable. So, we can say: It is very hotANDIt is absolutely boiling, but NOTIt is very boiling. The table below gives further examples of gradable and ungradable adjectives and the intensifiers used with them.
