adapt: to make fit (as for a new use) often by modification
adjust: to bring to a more satisfactory state
The subtle difference here is that adjustment involves making changes within the original design parameters of the item being adjusted. You can adjust the volume of your radio. You can adjust the position of your chair.
Adaptation involves modifying an item for a new purpose- one that was not originally anticipated in the item's design.
If someone says "I have a book of photographs by Diane Arbus", and you respond with "Can I see it?" or "Can I look at it?", there is no difference in meaning. "Look at" and "see" in this case mean the same thing: "I want to view/inspect the photographs/book."
If someone says, for example, "Did you want to speak to John? He's at Willie's Bar and Grill right now", and you say "Let's go (to) see him", it means "Let's go to Willie's Bar and Grill to visit John and talk with him", but if you say "Let's go to look at him", it means "Let's go to Willie's Bar and Grill and view/stare at/inspect John". John is being considered a person in the first sentence but an object (like a book of photographs or a statue) in the second.
In some languages, one verb is used for "look", "read", and "see" (Chinese speakers in Taiwan, for example, use the verb "kàn" (看) for all three even though there are three different verbs for those three English words. What "kàn" means in a particular sentence, though, depends on the context and what question it answers.
In English, "looking at a book", "seeing a book", and "reading a book" have three different meanings. To "look at" means to "inspect/view", to "see" means to "perceive with the eyes", and to "read" means to look at and (try to) "understand the words in the book" (the content/meaning).
Best Answer
is to hit someone with a closed fist, most likely in the face, as in boxing.
is to make a dull striking sound produced by hitting something
If you punch someone, that could result in knocking out some teeth. If you thump someone, it is figurative, meaning you hit them somehow to produce a dull sound. 'Thump' is much more commonly understood as a noun, somewhat onomatopoeic, the sound of the word like the sound itself.
To say 'I thumped him and knocked his teeth out' sounds strange because you would not expect a dull sound if teeth were dislodged as a result; you usually don't get a 'thumping' sound from hitting someone in the face hard enough to knock out teeth.
sounds natural (semantically that is).
