[Q]: It is quite easy to separate preferences, and configuration, but options, and settings have much similar meaning; So similar,in fact, that I can't pick one over another. Could you please describe the meaning of these two words? What is it common between them, and what is it different? I have removed 'software UI' from the title, as it seems to lead answers off topic. I'm genuinely interested in subtle difference in meaning of named words.
[A]: Options refers to things you may choose;you may select one over another. So, the options you chose are 'preferences'. Settings mostly implies the 'context' that the options you chose are in and is more like configuration. E.g; Color is 'setting'; red, green, blue e.t.c are options. Font is 'setting'; Arial, Times New roman are options. Settings: color, font


[Q]: I was wondering why we say 'something is missing' instead of 'something is missed'? If missed is an adjective then why we use it that way? E.g.: 'The sword is missing'.
[A]: Imagine you have a collection of objects including a sword, one day you can't see the sword and you don't know where it's gone, then you can say 'The sword is missing', meaning it's absent. Now imagine you had a sword and you gave it to someone, or you got rid of it, the point being you know where it's gone and you don't have it. You see a snake in your lounge and you wish you had your sword to cut its head, you miss the sword and you think 'the sword is missed' (passive).


[Q]: I'm wondering which one of these expressions is correct? This stuff or these stuff?.
