Sense: adverb/2
These adverbs can all raise degree, but they do not sound the same. 'Very' is the neutral everyday choice and works almost anywhere: very cold, very slow, very kind. 'Extremely' is stronger and slightly more formal. 'Amazingly' does more than raise degree: it shows the speaker is impressed or surprised by how good, cheap, fast, easy, or pleasant something is. 'Incredibly' is close, but it more often suggests that the degree is hard to believe. Compare these: a room can be very small, extremely quiet, amazingly cheap, or incredibly clean. If you only need simple degree, choose 'very'. If you want degree plus a feeling of admiring surprise, 'amazingly' fits best.
Etymology
Amazingly was formed in English by adding the adverb ending '-ly' to 'amazing'. That adjective comes from the verb 'amaze', an old English word that first meant to confuse or stun someone. Over time the idea moved from simple bewilderment to the modern sense of causing great surprise or admiration.
