Question: Question: I believe there is a term for a person who uses 'expert sounding' terminology and exudes confidence, even when their actual abilities are significantly short of their 'presentation'. Using 'wine' a subject.... if a person described a taste as: Magnificent bouquet, the esters resonate with hints of mulberry and asparagus. This must be an oak-matured red from Bordeaux. Perhaps.... 2003 vintage, that was a year when unusual rainfall produced an outstanding crop that had the same rich tannins. A person describing the wine like that has apparent confidence, apparent technical expertise, and so on. Yet, if he was a fraud, and knew nothing about wines, and the "wine" was really vinegar.... what would you call that person? Additionally, this would not be a one-off thing. This would be a person who consistently "bamboozles" people, and only when you dig below the posturing, or put them in the company of a 'real' expert, do you see the reality. A fraud, a cheat, an imposter. Those would be true, but I'm sure there's a word which also covers the confidence, charisma, and presentation style too. I just can't think of it. 
Answer: We can call this person a poseur or poser. The Wikipedia page provides a fairly good explanation of the term, its use, and its etymology. Pronouncing it as "poser" sounds hip in a surferish subculture way, while pronouncing it as "poseur" (Frenching it up, so to speak) can sound, ironically enough, affected. But appropriate when someone's showing false pedantry (not a single word, but a useful and relevant phrase), especially about French wine.

Answer: no


Question: Question: I am looking for a word that describes a person described in the description of the title. An example of such a person would be a person who comfortably passes the (easier) qualifiers and gradually performs even better as opponents get tougher in the final stages of a tournament. The person does not necessarily relax when he knows he can easily win, but "naturally" performs better as the stakes get higher. 
Answer: If the difficulty of the situation is due to competition with other people, then the person could be called competitive. Eager to do better than others in an activity, esp. trying to win in a sports activity:.

Answer: no


Question: 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".

Answer:
no
