question:
How does one correctly apply 'in which', 'of which', 'at which', 'to which', etc.? I'm confused with which one to apply when constructing sentences around these.
answer:
The trick to knowing how to use; of which, at which, in which, to which, from which is to analyse the prepositional phrases, phrasal verbs, verbs and prepositions: He /spoke of/ war and peace and many other topics that day. The topic /of which he spoke/ was complex. The verb here that means to speak about a topic is /to speak/ of a topic/: to mention The party /at which/ he spoke/ was noisy. Phrase: A party is held /at a place/. It is implied. The situation /in which/ we found ourselves was dire. Phrase: /to find oneself /in a situation. The bonds /from which/ we broke free were tight. phrase: to /break free/ from bonds. The town /to which/we were driving was 50 ks away. phrase: to /drive/ to a place. Summary (and not a complete answer but a general one): The preposition depends on the verb that takes a preposition, a phrasal verb that includes a preposition, or it depends on the prepositional phrase used. Also, there are many other prepositions that can be paired with which: under, during, about, over, etc.


question:
Could you tell me some suitable idioms to express this situation: A guy told you a joke, but it's not funny at all. In Japanese, we say 'He slipped' or 'His joke was so cold that the air got frozen,' for that situation. Are there any similar phrases in English?.
answer:
The phrase lame joke is broadly used to describe (idiomatic) An attempt at humor which is perceived to have been used previously to the point of being cliche, or was never funny to begin with. You could use 'His joke was lame', 'His joke was not even funny' or 'His joke was corny.' [Wiktionary, Merriam-Webster Learner's Dicitionary]


question:
I am creating a computer game in which the character needs to consume food in order to not starve to death. In the game I can display the level of how much food the character currently needs via 'hunger level' - the higher this value, the more desperately the character needs food. But what I want now is to turn that around, so that this level tells how full the stomach of the character is. In German we have a word for that, 'Sattigung', which means how full my stomach is (or better: how full it feels to me), it is basically the opposite of hunger. Is there a similar word in English, which means exactly that, the opposite of hunger? It might be something like 'saturation', but from what I can tell this word is usually used in a technical context, like in 'the saturation of a color'. Can I use that 'saturation' to describe the opposite of hunger of a human or animal, or is there a better word for that?.
answer:

I think the apter word is 'satiety' than 'saturation' in the OP's context. satiety thestateof beingcompletely satisfied,especiallywithfoodor pleasure, so that you could not have any more.
