Ex Input:
Question: I'm currently writing an article that includes two contexts of communication: effectiveness and competence. Incompetent people can misuse terminology all day and the ideas are effective and do technically work. However I'm looking for a word or term that has two or more meanings and the misuse of could lead to bodily harm or even death; this is to promote the idea of the aspect of competently communicating one's ideas. What word if not used competently could end up leading to injury or death in a context that most people could understand with little-to-no explanation? 
Answer: This may not be exactly what you are looking for, but might work in the context. inflammable Many people see the "in" as a negative prefix, and believe anything marked inflammable is flame retardant. However, both flammable and inflammable have the same meaning: ...both mean "capable of being easily ignited and of burning quickly." This makes no sense to the Modern English speaker. In English, we think of in- as a prefix that means "not": inactive means "not active," inconclusive means "not conclusive," inconsiderate means "not considerate." Therefore, inflammable should mean "not flammable." -Merriam Webster Because of this, volatile or combustible materials are often labeled as "flammable" to avoid a potentially hazardous misinterpretation.

Question: First of all, I am not a native English speaker and not very good in English too. I had a technical problem in my software project and thus took help of somebody. She helped me to find the right way to resolve my issue. Can I say her, "You are a path shower" to show my appreciation to her ? UPDATE: She always guides me when I am in trouble. Considering this, what more can I say her. 
Answer: Most of these answer are so very flowery! I would simply go with "thanks for your guidance". It's appropriate for both formal and informal settings (unlike several of the other answers...), and straightforward. You could even flash it up: "thanks for your consistent, excellent guidance on this project" and keep it not too "puppy on the heels".

Ex Output:
no

Question: Possible Duplicate: What is the correct possessive for nouns ending in s? Before you vote to close as a duplicate, note that these two questions deal with similar issues to this, but none of them address all three criteria of this question: The singular already ends with an s. I am dealing with multiple of the thing. I want the possessive of all of them in general. The singular is class, and the plural is classes. The singular possessive is class's (as addressed here). What is the plural possessive? Is it classes's, or classes'? 
Answer: It is classes', which sounds the same as the singular class's. I would have thought this was a general rule for plural nouns ending -s', -es' or -ies'.

Ex Output:

yes
