Input: Consider Input: Question: What do you call someone who knows all the gossip and stories about people in his neighborhood or surroundings, someone who's always informed. It doesn't have to be expressed in a word. Could be a sentence (e.g. she knows the ins and outs), but I'm looking for a better way to express it.
Answer: I recall hearing (NPR) about American words borrowed from the native language of slaves such as from African is the word hepacat (I think that I have spelled it correctly) "someone who is knowledgable about what is going on" from which is derived hepcat which leads to hipcat finally hip.

Output: no

Output: yes

Input: Consider Input: Question: I'm a non-native English speaker, and my automatic spellchecker seems to accept both therefore and therefor. Is one orthography preferred ? Is that a British vs. American difference ? Or an old vs. more recent orthography ? Or something else ?
Answer: Therefor means for that. For example: Here we sell guitars and accessories therefor. Therefor is one of a whole series of adverbs: thereof (of that), thereafter(after that), therein (in there), etc. If you are familiar with German - the Germanic sister of English - you can find a direct analogy there: for = fur therefor, for that = dafur (literally, therefor) Therefore, as you must know, means as a (logical) consequence.
Output: yes
